DANS UN PREMIER TEMPS, IL EST PRESENTE SYNTHETIQUEMENT LES PRINCIPAUX CONCEPTS CONCERNANT LES SYSTEMES A PARAMETRES DISTRIBUES; EN RAPPELANT LES PROBLEMES OCCASIONNES PAR L'APPROXIMATION DES SYSTEMES, D'ORDRE INFINI, PAR UN NOMBRE FINI D'EQUATIONS DIFFERENTIELLES ORDINAIRES. COMPTE TENU DES PARTICULARITES DE LA REPRESENTATION D'ETAT DES STRUCTURES FLEXIBLES, LA REDUCTION DU MODELE EST OBTENUE A PARTIR D'UNE MESURE DE L'ENERGIE COMMUNIQUEE EN SORTIE PAR CHAQUE MODE VIBRATOIRE EN REPONSE A UNE ENTREE TEST. LE PROBLEME DU POSITIONNEMENT DES CAPTEURS ET DES ACTIONNEURS EST CONSIDERE DE DEUX FACONS DISTINCTES: UNE PREMIERE APPROCHE CONSISTE A FAIRE LE PLACEMENT A PARTIR DES MESURES DU DEGRE DE COMMANDABILITE ET D'OBSERVABILITE. LA DEUXIEME APPROCHE ASSOCIE LE CALCUL DES LOIS DE COMMANDE AU PROBLEME DU PLACEMENT. DANS CE CAS, LA MESURE ADOPTEE PORTE SUR LA SOLUTION DE L'EQUATION DE RICCATI. GRACE A DES PROPRIETES DE CONCAVITE QUI DECOULENT DE L'UTILISATION DE CES MESURES, IL A ETE POSSIBLE DE METTRE EN UVRE LES PROCEDURES NECESSAIRES POUR RESOUDRE LE PROBLEME DE LOCATION OPTIMALE. POUR TENIR COMPTE DES VARIATIONS DES PARAMETRES DU MODELE, LA SYNTHESE DES LOIS DE COMMANDE EST REALISE PAR DES METHODES DE COMMANDE ROBUSTE, TOUT EN FAISANT APPARAITRE LE RAPPORT ENTRE LES EQUATIONS DU TYPE RICCATI MODIFIEES ET LA THEORIE DE JEUX POUR LES STRATEGIES DE NASH ET DE STACKELBERG. FINALEMENT, PLUSIEURS EXEMPLES SONT PRESENTES POUR ILLUSTRER LES METHODES DEVELOPPEES

Available in PDF, EPUB and Kindle. Book excerpt: Qu’il s’agisse de tâches de préhension versatile aux échelles du micromonde ou bien de tâches de manipulation fine ou dextre à une échelle dimensionnelle supérieure, la fonction de manipulation robotique nécessite l’utilisation de systèmes mécatroniques performants et précis. Dans la majorité des cas, ceux-ci mettent en jeu des mécanismes qui sont caractérisés par des phénomènes mécaniques de flexibilité. Ces phénomènes sont induits naturellement par l’emploi de certains composants technologiques constitutifs du système ou par la géométrie de certaines structures élancées. Il peut alors s’agir de micromanipulateurs à base de matériaux actifs, de bras manipulateurs légers, d’organes terminaux de préhension très intégrés sur le plan fonctionnel, voire de manipulateurs d’inspiration anthropomorphe. Aperçu des dernières avancées scientifiques et technologiques en la matière, cet ouvrage est destiné à toute personne intéressée par le champ de la robotique flexible et plus particulièrement par la manipulation.

Book excerpt: Dans cette thèse, les problématiques de la modélisation et du contrôle robuste de l'attitude des grandes structures spatiales flexibles sont considérées. Afin de satisfaire les performances de pointage requises dans les scénarios des futures missions spatiales, nous proposons d'optimiser directement une loi de commande d'ordre réduit sur un modèle de validation d'ordre élevé et des critères qui exploitent directement la structure du modèle. Ainsi, les travaux de cette thèse sont naturellement divisés en deux parties : une partie relative à l'obtention d'un modèle dynamique judicieusement structuré du véhicule spatial qui servira à l'étape de synthèse ; une seconde partie concernant l'obtention de la loi de commande.Ces travaux sont illustrés sur l'exemple académique du système masses-ressort, qui est la représentation la plus simple d'un système flexible à un degré de liberté. En complément, un cas d'étude sur un satellite géostationnaire est traité pour valider les approches sur un exemple plus réaliste d'une problématique industrielle.

Book excerpt: Le propos de ce travail est d'effectuer le contrôle actif d'une maquette de ballottement constituée d'une poutre encastrée-libre, dotée d'un réservoir en son extrémité. Il a d'abord s'agit de modéliser et dimensionner la structure. De par sa complexité, nous avons eu recours à un logiciel de calculs par éléments finis, qui a fourni les paramètres électromécaniques à partir desquels un modèle est obtenu. La loi de commande devra appréhender un contexte multi-modes et multivariables et être suffisamment robuste, les interactions fluide/structure et configurations de remplissage du réservoir étant vues comme des incertitudes autour d'un modèle nominal. La Commande Prédictive Généralisée a été choisie. Les résultats expérimentaux de l'emploi du GPC pour effectuer le contrôle actif sont probants. Au delà des performances du correcteur et de sa compacité, cette loi permet d'obtenir globalement le même comportement du système corrigé d'une configuration de remplissage du réservoir à l'autre.

Available in PDF, EPUB and Kindle. Book excerpt: Les systèmes d'entraînement de bandes flexibles sont utilisés dans la production d'une très grande variété de produits du quotidien mais également dans la métallurgie et dorénavant pour la production des nouvelles technologies. L'amélioration des systèmes industriels d'entraînement de bandes est un problème difficile car ils sont de grande dimension, non-linéaires, à paramètres variant et incertains. Ils possèdent un fort couplage entre les différentes parties (mécanique et commande) à cause de la bande qui relie les éléments. Il faut donc améliorer la chaîne de production par une approche pluridisciplinaire. Les objectifs sont de maîtriser les paramètres clés de ces systèmes afin de garantir les cadences de production et les précisions demandées de plus en plus importantes. Il faut également réduire les défauts les plus récurrents, notamment les plis de bande. Or jusqu'à présent seuls des modèles 1D étaient utilisés. Ils sont indispensables pour la synthèse de commande et les études fréquentielles mais ne permettent pas d'étudier des phénomènes complexes tels que les plis de bande. Une nouvelle approche d'étude de ces systèmes est développée. Dans un premier temps, des améliorations de structures de commandes sont proposées. Dans un second temps un modèle 3D par éléments finis utilisant un algorithme de dynamique multicorps flexibles est développé et utilisé pour étudier les plis de bande par comparaison à la théorie classique de prédiction de ces défauts. Dans un troisième temps un simulateur complet est développé comprenant le modèle 3D mécanique par élément finis couplé à la partie commande (co-simulation).

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the most recent research results on modeling and control of robot manipulators. Chapter 1 gives unified tools to derive direct and inverse geometric, kinematic and dynamic models of serial robots and addresses the issue of identification of the geometric and dynamic parameters of these models. Chapter 2 describes the main features of serial robots, the different architectures and the methods used to obtain direct and inverse geometric, kinematic and dynamic models, paying special attention to singularity analysis. Chapter 3 introduces global and local tools for performance analysis of serial robots. Chapter 4 presents an original optimization technique for point-to-point trajectory generation accounting for robot dynamics. Chapter 5 presents standard control techniques in the joint space and task space for free motion (PID, computed torque, adaptive dynamic control and variable structure control) and constrained motion (compliant force-position control). In Chapter 6, the concept of vision-based control is developed and Chapter 7 is devoted to specific issue of robots with flexible links. Efficient recursive Newton-Euler algorithms for both inverse and direct modeling are presented, as well as control methods ensuring position setting and vibration damping.

Book excerpt: The articles of this book were reported and discussed at the fifth international symposium on Advances in Robot Kinematics. As is known, the first symposium of this series was organised in 1988 in Ljubljana. The following meetings took place every other year in Austria, Italy, and Slovenia (Linz, Ferrara, Ljubljana, Portoroz Bernardin). It must be emphasised that the symposia run under the patronage of the International Federation for the Theory of Machinesand Mechanisms, IFToMM. In this period, Advances in Robot Kinematics has been able to attract the most outstanding authors in the area and also to create an optimum combination of a scientific pragmatism and a friendly atmosphere. Hence, it has managed to survive in a strong competition of many international conferences and meetings. In the most ancient way, robot kinematics is regarded as an application of the kinematics of rigid hodies. However, there are topics and problems that are typical for robot kinematics that cannot easily be found in any other scientific field. It is our belief that the initiative of Advances in Robot Kinematics has contributed to develop a remarkable scientific community. The present book is of interest to researchers, doctoral students and teachers, engineers and mathematicians specialising in kinematics of robots and mechanisms, mathematical modelling, simulation, design, and control of robots.

Available in PDF, EPUB and Kindle. Book excerpt: The Fourth International Conference on Advanced Robotics was held in Columbus, Ohio, U. S. A. on June 13th to 15th, 1989. The first two conferences in this series were held in Tokyo. The third was held in Versailles, France in October 1987. The International Conference on Advanced Robotics is affiliated with the International Federation of Robotics. This conference was sponsored by The Ohio State University. The American Society of Mechanical Engineers was a cooperating co-sponsor. The objective of the International Conference on Advanced Robotics is to provide an international exchange of information on the topic of advanced robotics. This was adopted as one of the themes for international research cooperation at a meeting of representatives of seven industrialized countries held in Williamsburg, U. S. A. in May 1983. The present conference is truly international in character with contributions from authors of twelve countries. (Bulgaria, Canada, France, Great Britain, India, Italy, Japan, Peoples Republic of China, Poland, Republic of China, Spain, United States of America.) The subject matter of the papers is equally diverse, covering most technical areas of robotics. The authors are distinguished. They are leaders in the field in their respective countries. The International Conference on Advanced Robotics has always particularly encouraged papers oriented to the design of robotic systems, or to research directed at advanced applications in service robotics, construction, nuclear power, agriculture, mining, underwater systems, and space systems.

Book excerpt: This volume contains 92 papers on the state-of-the-art in robotics research. In this volume topics on modelling and identification are treated first as they build the basis for practically all control aspects. Then, the most basic control tasks are discussed i.e. problems of inverse kinematics. Groups of papers follow which deal with various advanced control aspects. They range from rather general methods to more specialized topics such as force control and control of hydraulic robots. The problem of path planning is addressed and strategies for robots with one arm, for mobile robots and for multiple arm robots are presented. Also covered are computational improvements and software tools for simulation and control, the integration of sensors and sensor signals in robot control.

This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades, applications of dynamical analysis in advanced, often nonlinear, engineering systems have been evolved in a revolutionary way. In this context one can think of applications in aerospace engineering like satellites, in naval engineering like ship motion, in mechanical engineering like rotating machinery, vehicle systems, robots and biomechanics, and in civil engineering like earthquake dynamics and offshore technology. One could continue with this list for a long time. The application of advanced dynamics in the above fields has been possible due to the use of sophisticated computational techniques employing powerful concepts of nonlinear dynamics. These concepts have been and are being developed in mathematics, mechanics and physics. It should be remarked that careful experimental studies are vitally needed to establish the real existence and observability of the predicted dynamical phenomena. The interaction between nonlinear dynamics and nonlinear control in advanced engineering systems is becoming of increasing importance because of several reasons. Firstly, control strategies in nonlinear systems are used to obtain desired dynamic behaviour and improved reliability during operation, Applications include power plant rotating machinery, vehicle systems, robotics, etc. Terms like motion control, optimal control and adaptive control are used in this field of interest. Since mechanical and electronic components are often necessary to realize the desired action in practice, the engineers use the term mechatronics to indicate this field. If the desired dynamic behaviour is achieved by changing design variables (mostly called system parameters), one can think of fields like control of chaos.
