La priorisation humaine. Étude des corrélats cognitifs de l'évaluation des priorités by Benoît Valéry( )

1 edition published in 2017 in French and held by 1 WorldCat member library worldwide

La viabilité des systèmes de travail complexes repose en partie sur la capacité des opérateurs à y gérer des tâches concurrentes en fonction de leurs priorités respectives. Il s'agit là d'un processus critique qui, lorsqu'il est défaillant, peut amener à des erreurs de négligence ou de persévération sur certaines opérations. Les modèles actuels de la priorisation humaine présentent de nombreuses limites : ils sont souvent normatifs et ne rendent pas suffisamment compte de la façon dont les opérateurs utilisent effectivement l'information disponible dans l'environnement pour le calcul des priorités. Leur faible pouvoir descriptif ne permet pas réellement de comprendre les mécanismes cognitifs contributifs de l'erreur, spécialement dans des situations de surcharge mentale. Cette thèse, en adoptant l'approche de l'ergonomie cognitive, se donne pour objectif de mieux comprendre et décrire ces processus. Trois expérimentations fondamentales ont été menées, qui toutes mettaient les participants aux prises avec des situations de double-tâche, où divers attributs (difficulté, importance, marge d'erreur) des tâches étaient manipulés. Ces tâches reproduisaient des sollicitations des environnements complexes, comme la mémorisation, la surveillance, ou encore le diagnostic sous incertitude. L'ensemble des résultats souligne l'importance de la priorisation dans la bonne tenue des systèmes complexes, et suggère une sensibilisation accrue des opérateurs à ces phénomènes lors de leur formation, ainsi qu'une réflexion à plus long terme sur la présentation de l'information dans le contexte des interfaces homme-machine
Operational scenarios optimization for resupply of crew and cargo of an International gateway Station located near the Earth-Moon-Lagrangian point-2 by Stéphanie Lizy-Destrez( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

In the context of future human space exploration missions in the solar system (with an horizon of 2025) and according to the roadmap proposed by ISECG (International Space Exploration Coordination Group) [1], a new step could be to maintain as an outpost, at one of the libration points of the Earth-Moon system, a space station. This would ease access to far destinations as Moon, Mars and asteroids and would allow to test some innovative technologies, before employing them for far distant human missions. One of the main challenges will be to maintain permanently, and ensure on board crew health thanks to an autonomous space medical center docked to the proposed space station, as a Space haven. Then the main problem to solve is to manage the station servitude, during deployment (modules integration) and operational phase. Challenges lie, on a global point of view, in the design of the operational scenarios and, on a local point of view, in trajectories selection, so as to minimize velocity increments (energy consumption) and transportation duration (crew safety). Which recommendations could be found out as far as trajectories optimization is concerned, that would fulfill energy consumption, transportation duration and safety criterion? What would technological hurdles be to rise for the building of such Space haven? What would be performances to aim at for critical sub-systems? Expected results of this study could point out research and development perspectives for human spaceflight missions and above all, in transportation field for long lasting missions.Thus, the thesis project, presented here, aims at from global system life-cycle decomposition, to identify by phase operational scenario and optimize resupply vehicle mission. The main steps of this project consist in:- Bibliographical survey, that covers all involved disciplines like mission analysis (Astrodynamics, Orbital mechanics, Orthography, N-Body Problem, Rendezvous...), Applied Mathematics, Optimization, Systems Engineering....- Entire system life-cycle analysis, so as to establish the entire set of scenarios for deployment and operations (nominal cases, degraded cases, contingencies...) and for all trajectories legs (Low Earth Orbit, Transfer, Rendezvous, re-entry...)- Trade-off analysis for Space Station architecture- Modeling of the mission legs trajectories- Trajectories optimizationThree main scenarios have been selected from the results of the preliminary design of the Space Station, named THOR: the Space Station deployment, the resupply cargo missions and the crew transportation. The deep analysis of those three main steps sorted out the criticality of the rendezvous strategies in the vicinity of Lagrangian points. A special effort has been set on those approach maneuvers. The optimization of those rendezvous trajectories led to consolidate performances (in term of energy and duration) of the global transfer from the Earth to the Lagrangian point neighborhood and return. Finally, recommendations have been deduced that support the Lagrangian points importance for next steps of Human Spaceflight exploration of the Solar system
Guidage et pilotage d'un remorqueur magnétique spatial by Emilien Fabacher( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Remorquer des satellites peut être utiles pour de nombreuses raisons : les désorbiter ou ré-orbiter, nécessaire dans le cas des satellites en fin de vie, ou pour finaliser les lancements par exemple. Dans ce cas, cette manœuvre augmenterait la capacité des étages supérieurs de lanceurs. Plusieurs moyens peuvent être envisagés pour modifier l'orbite d'un satellite cible grâce à un autre satellite. Parmi eux, les concepts sans contact sont intéressants, car ils fournissent un moyen d'éviter le besoin d'interfaces normalisées. Ils permettent ausside ne pas réaliser d'amarrages non coopératifs, qui représentent une grande difficulté. Enfin, ils contribuent à réduire le risque de créer de nouveaux débris par collision. Dans cette thèse, nous proposons d'utiliser les forces magnétiques pour remorquer le satellite cible. En effet, de nombreux satellites, en particulier en orbite terrestre basse, sont équipés de magnéto-coupleur, utilisés pour le contrôle d'attitude. Un satellite chasseur équipé d'un dipôle magnétique puissant pourrait donc générer des forces sur la cible. Cependant, la création d'une force entre deux dipôles magnétiques génère automatiquement des couples sur les deux dipôles. Par conséquent, la viabilité d'un remorqueur magnétique spatial n'est a priori pas assurée, étant donné qu'appliquer en permanence des couples sur les deux satellites ne serait pas acceptable
Lateral stability and control of an aircraft equiped with a small fin by differential use of propulsion systems or by actuators such that butterfly airbrakes. Use of co-design methods by Eric Nguyen Van( )

1 edition published in 2020 in French and held by 1 WorldCat member library worldwide

The possibility to increase the performance of a transport aircraft through a relaxation of the directional static stability, also called weathercock stability, is studied in this thesis. A change of paradigm brought by the concept of distributed electric propulsion allows the consideration of an active use of differential thrust. This additional means of flight control and the reduction of the vertical tail are the main ideas explored in this work. In a first part, the directional static stability and controllability of an aircraft are evaluated to find the sizing flight conditions for the vertical tail. The contribution here is to take into account the specificities of the unconventional propulsion system. Mathematical tools are developed to trim the aircraft using differential thrust as a mean of directional control and aerodynamic tools are constructed to describe the variable vertical tail size and the aero-propulsive interactions taking place between a propeller and a wing. This analysis isolates a sizing flight condition, particularly the case of engine failure at take-off, for the vertical tail and leads to a significant reduction in surface area. It is also shown that the rudder control surface could be removed and replaced by differential thrust. In a second part, the flight dynamic aspects of an aircraft with a small vertical tail and differential thrust as the only means of directional control are studied. A methodology is proposed to answer the question of how should the vertical tail and propulsion system be designed to satisfy a set of prescribed flight handling qualities ? An automatic control architecture and co-design methodology relying on structured H1 control design and non convex optimisation tools are utilized and developed to manage the trade off between vertical tail size and engine bandwidth. This framework is used in the flight conditions defined in the first part and notably in presence of engine failures. In a last part, a means of experimental research is developed to contribute to an effort to produce experimental data on distributed electric propulsion. This flight demonstrator is specifically oriented toward the study of the lateral flight mechanics of an aircraft having a large portion of the wing embedded in the propeller slipstream. It was possible to identify the aerodynamic derivatives and their dependence on the thrust from the flight data to illustrate the particularity of flight dynamics with distributed propulsion and blown wing
La Phi-théorie : une approche pour la conception de lois de commande de vol des véhicules convertibles by Leandro Ribeiro Lustosa( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Since their debut in the 50s, vertical take-off and landing (VTOL) aircraft would only be flown by the most experienced pilots. Recent advances on low-cost inertial sensors, embedded computing and control technology -- on the other hand -- support stability augmentation systems (SAS) in mitigating unstable dynamic modes and allowing for inexperienced (or even autonomous) flight. Nearly all autopilot design techniques, however, rely on accurate mathematical descriptions of novel and thus unfamiliar architectures (e.g., number and positioning of propellers, number and positioning of fixed/variable aerodynamic surfaces). The present thesis establishes an unified framework, namely the Phi-theory, for assessing hybrid vehicles handling qualities and, moreover, designing appropriate stabilizing control laws. This study sets out to establish a tractable model for tail-sitting vehicles in view of control design and qualitative dynamics analysis. The proposed Phi-theory not only yields a numerically advantageous model but also extends our comprehension of tail-sitting vehicles. In sharp contrast with existent literature, the proposed model is globally non-singular, polynomial-like and bypasses the use of aerodynamic angles of attack and sideslip (both free-stream and propwash-induced!). Nevertheless, even if mathematically elegant, a mathematical model has practical use only if consistent with reality. This thesis shows this is the case by means of wind tunnel data and flight experiments. I strongly believe Phi-theory provides a fitting balance between model complexity and controller design simplicity
Planification d'une stratégie de navigation et de guidage pour des drones autonomes dans des milieux encombrés by Jean-Alexis Delamer( )

1 edition published in 2019 in French and held by 1 WorldCat member library worldwide

Avec la demande croissante pour l'utilisation de drones autonomes dans des milieuxurbains, la sûreté et l'efficacité de ces missions doivent être garanties. D'une part, il est connuque dans ces milieux la haute densité d'obstacles peut mettre en péril le vol en cas de collision.D'autre part, la capacité de navigation - estimation de la position et par conséquent l'erreurd'exécution - de ces drones dépend de la disponibilité et de la performance de leurs capteursembarqués qui varient selon l'environnement. Dans ce contexte, cette thèse propose un cadre deplanification de chemin sûr et efficace pour des drones en milieux encombrés. Nous avons fondénotre travail sur les Processus Décisionnel de Markov à Observabilité Mixte (MOMDP), carils permettent de modéliser des processus décisionnels à long terme tout en prenant en comptel'incertitude sur l'environnement et son observabilité mixte. Nous proposons une modélisationdu problème de planification qui intègre le système de guidage, navigation et contrôle (GNC),afin de mieux représenter la dynamique de la transition d'état pour un drone, ainsi que l'erreurd'exécution associée. La disponibilité probable, connue a priori, des capteurs embarqués, est aussiconsidérée dans le modèle. Afin d'assurer les contraintes de sûreté, nous proposons une fonctionde coût qui nous permet de raisonner en termes de taux de collision maximal à respecter. Cecipermet au planificateur de définir des politiques qui sont à la fois efficaces - minimisation dutemps de vol - et sûres, par le choix des chemins qui favorisent le respect du taux de collisionmaximal défini. De plus, dus à la complexité du problème de planification, nous proposons unnouvel algorithme de résolution "POMCP-GO", qui est basé sur deux algorithmes de l'état del'art. Nous avons exhaustivement évalué cet algorithme pour notre cadre d'application
Connectivity approach to mental state monitoring in the aeronautical context : from single operator to teammates by Kevin Verdière( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

Il existe un intérêt croissant pour la mise en œuvre d'outils permettant de monitorer les performances cognitives en environnement réaliste.Les avancées technologiques récentes ont permis la mise en oeuvre de dispositifs de monitoring portables, tels que l'électroencéphalogramme (EEG), la spectroscopie fonctionnelle proche infrarouge proche (fNIRS), l'eye tracking et l'électro-cardiogramme (ECG), afin d'étudier l'activité humaine dans une variété de configurations. Ces capteurs offrent d'intéressantes perspectives pour l'aviation via l'implémentation de systèmes d'interfaces cerveau-ordinateur passives et de technologie neuroadaptive assurant une exploitation plus sûre et plus efficace. Cependant, un problème critique consiste à extraire des marqueurs de la performance humaine pertinents et robustes pour la classification et pouvant être calculés en ligne. Ce doctorat a pour but d'évaluer les métriques de connectivité permettant de monitorer les performances cognitives. Nos travaux expérimentaux suggèrent que les métriques de connectivité en fNIRS (en particulier la cohérence en ondelettes) surpassent les métriques classiques lors de l'estimation de l'engagement dans un simulateur de vol réaliste ou de la fatigue dans des conditions réelles de vol. Nous avons ensuite mis en œuvre une nouvelle méthode, à savoir le compte de coïncidence retardée, pour évaluer la synchronie cardiaque dans un contexte d'hyperscanning. Les résultats ont révélés que cette métrique de connectivité était efficace pour détecter la coopération entre des coéquipiers face à une tâches exigeantes. De plus, les données EEG ont permis de classer la charge de travail et les niveaux de coopération que ce soit en utilisant les métriques issues d'un unique opérateur ou bien les données combinées des deux coéquipiers
Modélisation et contrôle d'un robot spatial flexible pour la capture d'un débris en rotation by Vincent Dubanchet( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Les débris en orbite sont actuellement une source de préoccupation majeure pour les acteurs du spatial et pour le reste de la population, comme en témoignent les articles de presse et les œuvres cinématographiques sur le sujet. En effet, la présence de ces objets menace directement les astronautes en mission et les satellites en opération. Parmi les nombreuses options déjà envisagées pour les traiter, cette thèse se concentre sur l'approche robotique, en proposant des outils et des méthodes de modélisation et de contrôle pour un satellite chasseur équipé d'un bras manipulateur. Des modèles dynamiques et des schémas de simulation optimisés sont ainsi développés pour tout système multi-corps constitué d'une base mobile supportant un nombre quelconque d'appendices rigides ou flexibles. Par la suite, les trajectoires de capture sont générées en conservant la continuité en accélération avec le mouvement naturel du point cible, dans le but de saisir aussi délicatement que possible le débris en rotation. Le suivi de cette trajectoire par l'effecteur du robot chasseur est alors assuré par une loi de contrôle à deux niveaux, dont le réglage repose sur la synthèse H1 structurée. Une étude de robustesse est également mise en place pour assurer la stabilité et les performances du système en boucle fermée, malgré les changements de configuration du bras. Enfin, la validation des travaux de thèse est réalisée par voie numérique avec un simulateur haute-fidélité, et par voie pratique avec un banc d'essais robotique incluant des composants physiques en temps réel
A port-Hamiltonian formulation of flexible structures. Modelling and structure-preserving finite element discretization by Andrea Brugnoli( )

1 edition published in 2020 in English and held by 1 WorldCat member library worldwide

This thesis aims at extending the port-Hamiltonian (pH) approach to continuum mechanicsin higher geometrical dimensions (particularly in 2D). The pH formalism has a strong multiphysicscharacter and represents a unified framework to model, analyze and control bothfinite- and infinite-dimensional systems. Despite the large literature on this topic, elasticityproblems in higher geometrical dimensions have almost never been considered. This workestablishes the connection between port-Hamiltonian distributed systems and elasticity problems.The originality resides in three major contributions. First, the novel pH formulationof plate models and coupled thermoelastic phenomena is presented. The use of tensor calculusis mandatory for continuum mechanical models and the inclusion of tensor variablesis necessary to obtain an intrinsic, i.e. coordinate free, and equivalent pH description. Second,a finite element based discretization technique, capable of preserving the structure of theinfinite-dimensional problem at a discrete level, is developed and validated. This methodologyrelies on an abstract integration by parts formula and can be applied to linear and non-linearhyperbolic and parabolic systems. Several finite elements for beams and plates structuresare proposed and tested. The discretization of elasticity problems in port-Hamiltonian formrequires the use of non-standard finite elements. Nevertheless, the numerical implementationis performed thanks to well-established open-source libraries, providing external users withan easy to use tool for simulating flexible systems in port-Hamiltonian form. Third, flexiblemultibody systems are recast in pH form by making use of a floating frame description validunder small deformations assumptions. This reformulation include all kinds of linear elasticmodels and exploits the intrinsic modularity of pH systems
Modélisation et commande d'interaction fluide-structure sous forme de système Hamiltonien à ports : Application au ballottement dans un réservoir en mouvement couplé à une structure flexible by Flávio Luiz Cardoso-Ribeiro( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

This thesis is motivated by an aeronautical issue: the fuel sloshing in tanksof very flexible wings. The vibrations due to these coupled phenomena can lead to problemslike reduced passenger comfort and maneuverability, and even unstable behavior. Thisthesis aims at developing new models of fluid-structure interaction based on the theory ofport-Hamiltonian systems (pHs). The pHs formalism provides a unified framework for thedescription of complex multi-physics systems and a modular approach for the coupling ofsubsystems thanks to interconnection ports. Furthermore, the design of controllers using pHsmodels is also addressed. PHs models are proposed for the equations of liquid sloshing based on 1D and 2D SaintVenant equations and for the equations of structural dynamics. The originality of the workis to give pHs models of sloshing in moving containers. The interconnection ports are used tocouple the sloshing dynamics to the structural dynamics of a beam controlled by piezoelectricactuators. After writing the partial differential equations of the coupled system using thepHs formalism, a finite-dimensional approximation is obtained by using a geometric pseudospectralmethod that preserves the pHs structure of the infinite-dimensional model at thediscrete level. The thesis proposes several extensions of the geometric pseudo-spectral method,allowing the discretization of systems with second-order differential operators and with anunbounded input operator. Experimental tests on a structure made of a beam connected to atank were carried out to validate both the pHs model of liquid sloshing in moving containersand the pseudo-spectral semi-discretization method. The pHs model was finally used to designa passivity-based controller for reducing the vibrations of the coupled system

Développement et mise en œuvre d'une approche psycho-physio-acoustique pour le contrôle temps réel de l'impact du bruit en cabine d'hélicoptère by Emilie Jahanpour( )

1 edition published in 2019 in French and held by 1 WorldCat member library worldwide

Environmental noise has well-known effects on humans. In the short term, it can be a source of stress, fatigue, or decreased alertness. However, the literature shows complex effects, it can, for example, be a source of pleasure and motivation. In the field of helicopter acoustics, cabin noise is particular because it has a wide frequency range (10-10000Hz). The noise of the main transmission gearbox is particularly unpleasant because it is tonal noise in frequency ranges (500-3000 Hz) close to speech (200-6000 Hz) to which humans are very sensitive. Passengers want to be able to work, read and rest without being annoyed, so one challenge for manufacturers is to improve sound comfort in the cabin. To reduce this noise, one solution is to use active noise control. Airbus Helicopters has developed a headrest system integrating speakers and microphones to generate an area around the passenger's head in which active noise control is performed. The addition of a multi-tone algorithm, designed to filter only emerging tones, allows a gain up to 4 dB(A), which represents a 15% reduction in discomfort. The purpose of this thesis was to define whether it is relevant to filter all these tones according to the passenger's current activity. In other words, this thesis aimed to better understand the impact of different helicopter cabin noises on cognitive performance and passenger comfort through subjective, behavioural (performance, oculometry) and psychophysiological (electroencephalography, electrocardiography) measurements. In order to simulate a passenger's activity, three tasks were selected: a "working" task (combining mental calculation, reasoning, and working memory), a reading task and finally a resting task. The results were compared with those obtained by the acoustic comfort scale developed by Airbus Helicopters. We find a good correspondence between this scale and our results. In addition, our behavioural and psychophysiological results show that, generally short exposure to helicopter noises has limited deleterious effects on task performance and creates only a slight increase in stress level, observable through the cerebral and cardiac activity. However, the subjective feeling is most impacted by noise, with a negative feeling associated to the noises with the most tones
Human-robotic performance quantification under time-delay for lunar mission control scenarios by Shahrzad Hosseini( )

1 edition published in 2020 in English and held by 1 WorldCat member library worldwide

The Space Exploration Strategy of the Agency requires an affordable and efficient approach to operating and controlling space systems. In the exploration programme an optimum approach to integrate human decision makers in orbit and on the ground must be found. In the proposed activity the next logical step is taken: a systematic analysis of existing experimental data and execution of new experiments to find the most efficient and affordable approach to human-robotic integrated technology and operations. In a first phase, existing experimental data from METERON, but also large datasets from non- space operations will be processed to provide a clear metric of operations performance with respect to quantitative parameters of communication link properties, robotic asset capabilities, level of automation, and operator environment. The second phase of the study will define and implement affordable ground-based experiments with robotic assets deployed in analogue environments and operators hosted in a simulation environment. The third and final phase of the activity will culminate in the drafting of three documents in addition to the PhD thesis: 1) Crew-training manual for operating human-robotic technology on ESA exploration missions 2) Guideline for assessing human performance for human-robotic operations in the frame of astronaut selection 3) Human-robotic technology assessment document
Contrôle de l'état attentionnel en conditions aéronautiques écologiques par imagerie cérébrale by Gautier Durantin( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

L'état attentionnel de l'opérateur est un des précurseurs de l'erreur humaine dans les systèmes complexes. Cela est particulièrement vrai en aéronautique, où la sécurité dépend en premier lieu de la capacité à réagir rapidement et correctement. Les niveaux de complexité associés à la gestion de tels systèmes aboutissent à des niveaux de charge mentale et d'engagement de l'opérateur en constante variation, qui peuvent être prédicteurs de sa performance. Ce projet de recherche adopte une démarche de Neuroergonomie, et vise à estimer l'état attentionnel en conditions écologiques par l'utilisation de mesures cérébrales. Nous avons tout d'abord étudié le comportement de l'opérateur soumis à des niveaux de demande extrêmes à l'aide de mesures cérébrales et psycho-physiologiques. Les résultats de ces études nous ont conduits au développement d'un nouveau cadre théorique centré sur l'engagement de l'opérateur pour estimer son état attentionnel. De plus, nous avons étudié différentes techniques de traitement du signal de manière à rendre possible l'utilisation des mesures cérébrales en temps réel en situation écologique, en vue du développement d'interfaces cerveau-machine pour assister l'opérateur
Conception préliminaire de surfaces de contrôle et lois de commande pour configurations d'avions non conventionnelles by Yann Denieul( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Next generation of civil transport aircraft is likely to be a radical change in overallconfiguration compared to traditional tube-and-wing design. From a handling qualities perspective,current trend in modern airliners is to evolve towards more and more unstable aircraft, bothfrom longitudinal and lateral-directional point of view. As a consequence future aircraft may notbe controllable by human operator without stabilizing control laws. It then becomes necessaryto consider flight control systems contribution early in the design phase for control surfaces,empennages and actuators sizing, as opposed to traditional way of working dealing only withopen-loop criteria for preliminary sizing. Instead of an iterative process of sizing and controllaws synthesis, we propose to concurrently optimize control surfaces, actuators and flight controllaws taking into account longitudinal and lateral instability as well as industrial structure forcontrollers, for unstable configurations such as Blended Wing-Body (BWB). This “co-design”procedure enables sizing of physical aircraft parameters taking into account benefits from feedbackstabilization for counteracting external disturbance such as atmospheric turbulence, thus leadingto safer and more optimal aircraft configurations
Caractérisation de la surdité inattentionnelle, application à la sécurité aérienne by Louise Giraudet( )

1 edition published in 2015 in French and held by 1 WorldCat member library worldwide

The analysis of airplane accidents has recently highlighted the crucial role of humanoperators, their mistakes having potential dramatic consequences. A specific type ofhuman error remains little discussed: inattentional deafness, which is defined as thetemporary inability to hear or to become aware of auditory information. In aeronautics,this cognitive failure is obviously critical because it can lead to the omission of auditoryalarms. The first challenge of this research project is to define behavioral and physiologicalcharacteristics of inattentional deafness. For this purpose, we focused on the twofundamental jobs in aviation safety and subjected to auditory alarms: piloting and airtraffic control. We planned to highlight the contextual conditions favoring the appearanceof inattentional deafness, in particular the operators' workload. A second challenge was toidentify potential adaptation in the interfaces with pilots and air traffic controllers toprevent or limit the apparition inattentional deafness. To address these issues, threeexperiments were conducted. The first experiment studied the impact of workload on thetreatment of auditory alarms during a landing task. It was determined that P3b was anindicator of deafness. The second experiment focused on the impact of design visualalarms on cognitive processing abilities auditory alarms, as part of air traffic control. Theresults showed a restoration of auditory P300 with the enhanced visual design us. Finally,the last experiment tested the relevance of eye measurements to detect contexts favoringinattentional deafness. These results open promising possibilities for prevention anddetection of inattentional deafness in critical positions of aviation safety
