Download or read book Contribution à la commande robuste de la machine asynchrone à double alimentation written by Georges Salloum and published by . This book was released on 2007 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse apporte une contribution aux méthodes d’analyse et de synthèse de la commande robuste des Machines Asynchrones à Double Alimentation alimentées par deux onduleurs de tension. Nous introduisons, au début, sa commande vectorielle avec capteurs mécaniques. Ce chapitre se distingue par une nouvelle approche pour découpler les courants de la MADA conduisant à un calcul simplifié des correcteurs. Il se termine par une étude prouvant la robustesse du découplage et de la commande vis-à-vis des variations paramétriques de la machine. La commande robuste de la MADA, par l'approche H∞, est ensuite abordée en faisant une comparaison entre quatre stratégies de contrôle. Une étude par mu-analyse de la robustesse en stabilité et en performance offre un critère de choix du correcteur. A la fin, nous abordons la commande robuste de la MADA sans capteurs mécaniques en travaillant sur des méthodes d’estimation ou d'observation : MRAS, filtre de KALMAN et l'estimateur fréquentiel.

Book Synopsis Contribution à la commande et à l'estimation des flux et constante de temps rotoriques de la machine asynchrone by : K. Pascal Olivier Asseu
Download or read book Contribution à la commande et à l'estimation des flux et constante de temps rotoriques de la machine asynchrone written by K. Pascal Olivier Asseu and published by . This book was released on 2000 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le moteur asynchrone constitue un sytème multivariable non linéaire et complexe où des paramètres varient avec la température ou l'état magnétique. Cette nature non linéaire nous a donc amené, dans ce travail, à proposer une stratégie de commande non linéaire afin de découpler les courants statoriques du moteur dans un repère (d, q) orienté selon le principe de la commande vectorielle. Le contexte naturellement bruité du moteur associé à un ondulateur ainsi que les variations paramétriques nous ont conduit à une démarche robuste. Ainsi nous avons réalisé la synthèse des correcteurs H∞ dans le but de maîtriser efficacement la dynamique des courants statoriques. La connaissance du flux et de la constante de temps rotoriques étant nécessaire pour établir les lois de commande et s'affranchir au mieux des variations paramétriques, en particulier celle de la constante de temps rotorique, nous avons mis en oeuvre des algorithmes d'observation par modes glissants discret étendu d'ordre complet et réduit réalisant une estimation en ligne des flux et constante de temps rotoriques. Dans la phase terminale la commande linéarisante et l'observateur sont validés puis confirmés par des simulations et une implantation en temps réel sur un banc moteur

Book Synopsis Numerical Methods for Partial Differential Equations by : Sandip Mazumder
Download or read book Numerical Methods for Partial Differential Equations written by Sandip Mazumder and published by Academic Press. This book was released on 2015-12-01 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical Methods for Partial Differential Equations: Finite Difference and Finite Volume Methods focuses on two popular deterministic methods for solving partial differential equations (PDEs), namely finite difference and finite volume methods. The solution of PDEs can be very challenging, depending on the type of equation, the number of independent variables, the boundary, and initial conditions, and other factors. These two methods have been traditionally used to solve problems involving fluid flow. For practical reasons, the finite element method, used more often for solving problems in solid mechanics, and covered extensively in various other texts, has been excluded. The book is intended for beginning graduate students and early career professionals, although advanced undergraduate students may find it equally useful. The material is meant to serve as a prerequisite for students who might go on to take additional courses in computational mechanics, computational fluid dynamics, or computational electromagnetics. The notations, language, and technical jargon used in the book can be easily understood by scientists and engineers who may not have had graduate-level applied mathematics or computer science courses. Presents one of the few available resources that comprehensively describes and demonstrates the finite volume method for unstructured mesh used frequently by practicing code developers in industry Includes step-by-step algorithms and code snippets in each chapter that enables the reader to make the transition from equations on the page to working codes Includes 51 worked out examples that comprehensively demonstrate important mathematical steps, algorithms, and coding practices required to numerically solve PDEs, as well as how to interpret the results from both physical and mathematic perspectives

Book Synopsis Quantum Communications and Cryptography by : Alexander V. Sergienko
Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.

Book Synopsis Optimal Shape Design for Elliptic Systems by : O. Pironneau
Download or read book Optimal Shape Design for Elliptic Systems written by O. Pironneau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of optimal shape design can be arrived at by asking the following question: "What is the best shape for a physical system?" This book is an applications-oriented study of such physical systems; in particular, those which can be described by an elliptic partial differential equation and where the shape is found by the minimum of a single criterion function. There are many problems of this type in high-technology industries. In fact, most numerical simulations of physical systems are solved not to gain better understanding of the phenomena but to obtain better control and design. Problems of this type are described in Chapter 2. Traditionally, optimal shape design has been treated as a branch of the calculus of variations and more specifically of optimal control. This subject interfaces with no less than four fields: optimization, optimal control, partial differential equations (PDEs), and their numerical solutions-this is the most difficult aspect of the subject. Each of these fields is reviewed briefly: PDEs (Chapter 1), optimization (Chapter 4), optimal control (Chapter 5), and numerical methods (Chapters 1 and 4).
