Download or read book Springer Handbook of Robotics written by Bruno Siciliano and published by Springer. This book was released on 2016-07-27 with total page 2259 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this handbook provides a state-of-the-art overview on the various aspects in the rapidly developing field of robotics. Reaching for the human frontier, robotics is vigorously engaged in the growing challenges of new emerging domains. Interacting, exploring, and working with humans, the new generation of robots will increasingly touch people and their lives. The credible prospect of practical robots among humans is the result of the scientific endeavour of a half a century of robotic developments that established robotics as a modern scientific discipline. The ongoing vibrant expansion and strong growth of the field during the last decade has fueled this second edition of the Springer Handbook of Robotics. The first edition of the handbook soon became a landmark in robotics publishing and won the American Association of Publishers PROSE Award for Excellence in Physical Sciences & Mathematics as well as the organization’s Award for Engineering & Technology. The second edition of the handbook, edited by two internationally renowned scientists with the support of an outstanding team of seven part editors and more than 200 authors, continues to be an authoritative reference for robotics researchers, newcomers to the field, and scholars from related disciplines. The contents have been restructured to achieve four main objectives: the enlargement of foundational topics for robotics, the enlightenment of design of various types of robotic systems, the extension of the treatment on robots moving in the environment, and the enrichment of advanced robotics applications. Further to an extensive update, fifteen new chapters have been introduced on emerging topics, and a new generation of authors have joined the handbook’s team. A novel addition to the second edition is a comprehensive collection of multimedia references to more than 700 videos, which bring valuable insight into the contents. The videos can be viewed directly augmented into the text with a smartphone or tablet using a unique and specially designed app. Springer Handbook of Robotics Multimedia Extension Portal: http://handbookofrobotics.org/

Available in PDF, EPUB and Kindle. Book excerpt: Ce mémoire est consacré à la stabilisation de systèmes non linéaires. L'étude se décompose en deux parties. La première partie est consacrée au problème de la stabilisation des systèmes non linéaires non réguliers. Nous nous sommes intéressés à des résultats classiques de stabilisation des systèmes non linéaires. Nous avons considéré un problème de stabilisation par retour d'état et un problème de stabilisation par ajout d'intégrateurs qui nécessitent la régularité des champs de vecteurs des systèmes considérés. Nous avons affaibli ces hypothèses de régularité en développant des résultats applicables aux systèmes non réguliers. La deuxième partie du mémoire concerne la stabilisation des systèmes différentiels fonctionnels de type retardé. Nous avons tout d'abord considéré un problème de stabilisation par retour d'état sans mémoire. Des conditions simples de stabilité asymptotique du système en boucle fermée ont été établies et une classe de lois de commandes stabilisantes a été proposée en utilisant la théorie de Lyapunov-Krasovskii. Des résultats de la théorie de la commande H[infini] nous ont permis de formuler des conditions de stabilité sous forme fréquentielle, ou en terme de spectre d'une matrice hamiltonienne. Nous avons ensuite traité le problème de la stabilisation par commande basée observateur pour ces systèmes. Une classe d'observateurs non linéaires à retards a été définie et l'analyse de la stabilité asymptotique du système en boucle fermée a été réalisée. Enfin, nous avons abordé le problème de la commande par mode de glissement pour une classe de systèmes présentant des perturbations additives bornées. Nous avons présenté une méthode de synthèse de lois de commandes par mode de glissement, bien adaptée à ce type de problème. Des conditions suffisantes pour générer le mode de glissement ont été proposées et la stabilité de la dynamique en mode de glissement a été analysée

Book Synopsis Robotique flexible : Manipulation multi-échelle by : GROSSARD Mathieu
Download or read book Robotique flexible : Manipulation multi-échelle written by GROSSARD Mathieu and published by Lavoisier. This book was released on 2013-07-01 with total page 395 pages. 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 Synopsis Analysis and Control of Underactuated Mechanical Systems by : Amal Choukchou-Braham
Download or read book Analysis and Control of Underactuated Mechanical Systems written by Amal Choukchou-Braham and published by Springer Science & Business Media. This book was released on 2013-11-18 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides readers with tools for the analysis, and control of systems with fewer control inputs than degrees of freedom to be controlled, i.e., underactuated systems. The text deals with the consequences of a lack of a general theory that would allow methodical treatment of such systems and the ad hoc approach to control design that often results, imposing a level of organization whenever the latter is lacking. The authors take as their starting point the construction of a graphical characterization or control flow diagram reflecting the transmission of generalized forces through the degrees of freedom. Underactuated systems are classified according to the three main structures by which this is found to happen—chain, tree, and isolated vertex—and control design procedures proposed. The procedure is applied to several well-known examples of underactuated systems: acrobot; pendubot; Tora system; ball and beam; inertia wheel; and robotic arm with elastic joint. The text is illustrated with MATLABsup®/sup/Simulink® simulations that demonstrate the effectiveness of the methods detailed./ppReaders interested in aircraft, vehicle control or various forms of walking robot will be able to learn from iUnderactuated Mechanical Systems

Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse est une contribution aux problèmes de la stabilité au sens de Lagrange et de la stabilisation par retour d'état des systèmes non linéaires. Elle concerne essentiellement les systèmes homogènes. Un premier résultat concerne la stabilité au sens de Lagrange d'une classe de systèmes quadratique tridimensionnels. Plus précisément, on étudie les champs définis sur les cylindres. Dans la deuxième partie de ce travail, nous présentons une condition nécessaire et suffisante pour la stabilisation, par une loi de commande au moins continue, des systèmes polynomiaux homogènes par rapport à une dilatation. Dans le cas d'une dilatation standard, nous proposons explicitement un feedback stabilisant polynomial. Finalement, les derniers types de résultats concernent le problème de la stabilisation par feedback dynamique. Nous donnons une nouvelle démonstration d'un résultat bien connu dans la théorie de la stabilisation dit "lemme des intégrateurs". Cette nouvelle approche permet de donner explicitement le feedback stabilisant pour le système augmenté, dans des situations où l'ancienne méthode montre seulement l'existence. De plus, le feedback proposé est plus régulier

Book Synopsis Advances in Time-Delay Systems by : Silviu-Iulian Niculescu
Download or read book Advances in Time-Delay Systems written by Silviu-Iulian Niculescu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the mathematical description of a physical or biological process, it is a common practice \0 assume that the future behavior of Ihe process considered depends only on the present slate, and therefore can be described by a finite sct of ordinary diffe rential equations. This is satisfactory for a large class of practical systems. However. the existence of lime-delay elements, such as material or infonnation transport, of tcn renders such description unsatisfactory in accounting for important behaviors of many practical systems. Indeed. due largely to the current lack of effective metho dology for analysis and control design for such systems, the lime-delay elements arc often either neglected or poorly approximated, which frequently results in analysis and simulation of insufficient accuracy, which in turns leads to poor performance of the systems designed. Indeed, it has been demonstrated in the area of automatic control that a relatively small delay may lead to instability or significantly deteriora ted perfonnances for the corresponding closed-loop systems.
Book Synopsis Stabilization of Linear Systems by : Vasile Dragan
Download or read book Stabilization of Linear Systems written by Vasile Dragan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main problems in control theory is the stabilization problem consisting of finding a feedback control law ensuring stability; when the linear approximation is considered, the nat ural problem is stabilization of a linear system by linear state feedback or by using a linear dynamic controller. This prob lem was intensively studied during the last decades and many important results have been obtained. The present monograph is based mainly on results obtained by the authors. It focuses on stabilization of systems with slow and fast motions, on stabilization procedures that use only poor information about the system (high-gain stabilization and adaptive stabilization), and also on discrete time implementa tion of the stabilizing procedures. These topics are important in many applications of stabilization theory. We hope that this monograph may illustrate the way in which mathematical theories do influence advanced technol ogy. This book is not intended to be a text book nor a guide for control-designers. In engineering practice, control-design is a very complex task in which stability is only one of the re quirements and many aspects and facets of the problem have to be taken into consideration. Even if we restrict ourselves to stabilization, the book does not provide just recipes, but it fo cuses more on the ideas lying behind the recipes. In short, this is not a book on control, but on some mathematics of control.

This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Control of Boundaries and Stabilization written by Jacques Simon and published by Springer. This book was released on 2006-02-06 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present proceedings volume is devoted to two subjects. Stabilization with emphasis on exact controllability: considering a physical system, such as a vibrating plate, one can reach a steady state in a finite time by acting on the boundary. Control of boundaries: given a physical system find the geometry of the domain (optimal shape) which minimizes a cost related to the solution of a boundary value problem in this domain, for example find a minimum drag profile. Many lectures included mathematical analysis as well as engineering applications and numerical simulation.
Book Synopsis Control Methods for Electrical Machines by : Rene Husson
Download or read book Control Methods for Electrical Machines written by Rene Husson and published by John Wiley & Sons. This book was released on 2013-03-01 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The type of control system used for electrical machines depends on the use (nature of the load, operating states, etc.) to which the machine will be put. The precise type of use determines the control laws which apply. Mechanics are also very important, because they affect performance. Another factor of essential importance in industrial applications is operating safety. Finally, the problem of how to control a number of different machines, whose interactions and outputs must be coordinated, is addressed and solutions are presented. These and other issues are addressed here by a range of expert contributors, each of whom are specialists in their particular field. This book is primarily aimed at those involved in complex systems design, but engineers in a range of related fields such as electrical engineering, instrumentation and control, and industrial engineering, will also find this a useful source of information.
