Available in PDF, EPUB and Kindle. Book excerpt: L'ASSERVISSEMENT DES SYSTEMES PEUT SE DEFINIR COMME LA RECHERCHE D'UNE LOI DE COMMANDE DEVANT SATISFAIRE DES CRITERES DE STABILITE, DE TEMPS DE REPONSE, DE REJET DE PERTURBATIONS, DE PASSIVITE, DE BORNES SUR LA COMMANDE, DE SATURATIONS DE CERTAINES SORTIES OU DE ROBUSTESSE PAR RAPPORT A DES INCERTITUDES PARAMETRIQUES. REMPLIR CE CAHIER DES CHARGES POUR UN SYSTEME LINEAIRE EST DEJA UN PROBLEME DIFFICILE EN SOI. LA MOTIVATION PRINCIPALE DE LA THESE EST DE PROPOSER UNE METHODOLOGIE DE SYNTHESE DE CORRECTEUR QUI GARANTISSE SIMULTANEMENT CES SPECIFICATIONS POUR UNE LARGE CLASSE DE SYSTEMES NON-LINEAIRES INCERTAINS. LES PROBLEMES NUMERIQUES, DITS DE PRECISION FINIE, RENCONTRES LORS DE L'IMPLEMENTATION DU CORRECTEUR DANS UN SYSTEME REEL SONT AUSSI ABORDES. LES TECHNIQUES PROPOSEES DE RECHERCHE DE LOI DE COMMANDE ROBUSTE REPOSENT SUR LA TRADUCTION DES CONTRAINTES SOUS LA FORME DE PROBLEMES D'OPTIMISATION CONVEXE. UNE FORMULATION DES CONDITIONS DITE PAR INEGALITES MATRICIELLES LINEAIRES (LMI) PERMET ALORS, GRACE A DE RECENTES AVANCEES DANS LE DOMAINE DE L'OPTIMISATION PAR POINTS INTERIEURS, DE SYNTHETISER NUMERIQUEMENT UNE LOI DE COMMANDE. CETTE APPROCHE REPRESENTE UN BON COMPROMIS ENTRE CALCULABILITE ET COMPLEXITE DES CONDITIONS DE SYNTHESE. DES ALGORITHMES SONT ALORS DEFINIS, ADAPTES A LA COMMANDE DE DIFFERENTS TYPES DE SYSTEME, ET DES EXEMPLES D'APPLICATION SONT TRAITES. UN LOGICIEL, SOUS LA FORME D'UNE BOITE A OUTILS MATLAB, A ETE DEVELOPPE POUR PERMETTRE A UN INGENIEUR AUTOMATICIEN D'UTILISER LES TECHNIQUES DEVELOPPEES DANS LA THESE DE MANIERE TRANSPARENTE ET SANS CONNAISSANCES PRE-REQUISES EN OPTIMISATION CONVEXE.

Book excerpt: Cette thèse propose d'étudier la robustesse des commandes issues de la théorie des jeux adaptée aux systèmes multientrées, multiobjectifs. De façon générale les stratégies avec une structure d'information en boucle ouverte présentent des propriétés faibles de robustesse et ne peuvent être déterminées qu'a posteriori. Des exemples exhibent certaines limites. Les stratégies avec une structure d'information en boucle fermée sont beaucoup plus ardues à déterminer. Dans le cas d'une stratégie de Nash, un nouvel algorithme utilisant le manque de confiance est présenté pour résoudre les équations couplées algébriques de type Riccati. Pour une stratégie de Stackelberg avec une structure d'information en boucle fermée les conditions nécessaires et suffisantes sont déterminées et appliquées au problème de commande mixte H2 / Hinf. Enfin une extension à des systèmes comportant des incertitudes paramétrées mène à la résolution itérative d'une association non convexe de problèmes d'optimisation.

Book excerpt: DE NOMBREUX PROBLEMES DE COMMANDE DES SYSTEMES S'EXPRIMENT SOUS LA FORME D'INEGALITES MATRICIELLES LINEAIRES (LMI). DES AVANCEES RECENTES EN OPTIMISATION CONVEXE ONT ABOUTI A DES ALGORITHMES DE RESOLUTION EFFICACES : LES PROBLEMES D'OPTIMISATION LMI PEUVENT ETRE CONSIDERES COMME RESOLUS, C'EST-A-DIRE AISEMENT CALCULABLES. C'EST LA RAISON QUI A MOTIVE CE TRAVAIL DE THESE CONSACRE A LA FORMULATION DE PROBLEMES DE COMMANDE EN PROBLEMES LMI. L'IDEE CENTRALE DE L'APPROCHE PROPOSEE CONSISTE A ANALYSER LES PROPRIETES DES SYSTEMES LINEAIRES A PARAMETRES VARIANTS EN DEFINISSANT DES CRITERES DE PERFORMANCE SE FORMULANT COMME DES LMI. UNE PROPRIETE INTRINSEQUE DES LMI PERMET DE LES ASSOCIER ET DONC DE RESOUDRE DES PROBLEMES D'ANALYSE COMPRENANT PLUSIEURS CRITERES (ANALYSE MULTICRITERE). SUIVANT LA CONFIGURATION DU SYSTEME (MESURE COMPLETE OU NON DE L'ETAT, MESURE DE LA PERTURBATION, SATURATION EN ENTREE), LA SYNTHESE MULTICRITERE DE LOIS DE COMMANDE DE STRUCTURES DIFFERENTES (RETOUR D'ETAT, RETOUR DE SORTIE ET SEQUENCEMENT DE GAINS) EST ETUDIEE. DANS CHAQUE CAS, UNE DEMARCHE IDENTIQUE CONDUIT AUX CONDITIONS DE SYNTHESE QUI SONT UN COMPROMIS INTERESSANT ENTRE LE CONSERVATISME ET LA CALCULABILITE DE LA SOLUTION DU PROBLEME DE SYNTHESE. A PARTIR DE CETTE DERNIERE, LES PARAMETRES DE LA LOI DE COMMANDE SONT DETERMINES DIRECTEMENT PAR DES FORMULES EXPLICITES OU PAR DEFAUT EN RESOLVANT UN AUTRE PROBLEME LMI. EN MARGE DES OUTILS CLES EN MAIN PRESENTES DANS CETTE THESE ADAPTES A DES CLASSES IMPORTANTES DE PROBLEMES DE L'INGENIEUR, LA MODULARITE DE L'APPROCHE, LA TRAME DU MEMOIRE OFFRENT AU LECTEUR LA POSSIBILITE DE CONSTRUIRE DES OUTILS D'ANALYSE ET DE SYNTHESE A LA CARTE POUR UN PROBLEME DE COMMANDE SPECIFIQUE.

Download or read book Semiparametric Theory and Missing Data written by Anastasios Tsiatis and published by Springer Science & Business Media. This book was released on 2007-01-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes current knowledge regarding the theory of estimation for semiparametric models with missing data, in an organized and comprehensive manner. It starts with the study of semiparametric methods when there are no missing data. The description of the theory of estimation for semiparametric models is both rigorous and intuitive, relying on geometric ideas to reinforce the intuition and understanding of the theory. These methods are then applied to problems with missing, censored, and coarsened data with the goal of deriving estimators that are as robust and efficient as possible.

Download or read book Graphics Recognition Algorithms and Applications written by Dorothea Blostein and published by Springer. This book was released on 2014-10-08 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents refereed and revised papers presented at GREC 2001, the 4th IAPR International Workshop on Graphics Recognition, which took place in Kingston, Ontario, Canada in September 2001. Graphics recognition is a branch of document image analysis that focuses on the recognition of two-dimensional notations such as engineering drawings, maps, mathematical notation, music notation, tables, and chemical structure diagrams. Due to the growing demand for both o?-line and on-line document recognition systems, the ?eld of graphics recognition has an excitingand promisingfuture. The GREC workshops provide an opportunity for researchers at all levels of experience to share insights into graphics recognition methods. The workshops enjoy strongparticipation from researchers in both industry and academia. They are sponsored by IAPR TC-10, the Technical Committee on Graphics Recog- tion within the International Association for Pattern Recognition. Edited v- umes from the previous three workshops in this series are available as Lecture Notes in Computer Science, Vols. 1072, 1389, and 1941. After the GREC 2001 workshop, authors were invited to submit enhanced versions of their papers for review. Every paper was evaluated by three reviewers. We are grateful to both authors and reviewers for their careful work during this review process. Many of the papers that appear in this volume were thoroughly revised and improved, in response to reviewers’ suggestions.

The 25 revised full papers presented were carefully selected from numerous submissions. Graphics recognition is a subfield of document image analysis that deals with graphical entities in engineering drawings, sketches, maps, architectural plans, musical scores, mathematical notation, tables, and diagrams. Accordingly the conference papers are organized in 5 technical sessions, covering the topics such as map and ancient documents, symbol and logo recognition, sketch and drawings, performance evaluation and challenge processing.

Download or read book Invariants for Pattern Recognition and Classification written by Marcos A. Rodrigues and published by World Scientific. This book was released on 2000 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was conceived from the realization that there was a need to update recent work on invariants in a single volume providing a useful set of references and pointers to related work. Since the publication in 1992 of J L Mundy and A Zisserman's Geometric Invariance in Computer Vision, the subject has been evolving rapidly. New approaches to invariants have been proposed and novel ways of defining and applying invariants to practical problem solving are testimony to the fundamental importance of the study of invariants to machine vision. This book represents a snapshot of current research around the world. A version of this collection of papers has appeared in the International Journal of Pattern Recognition and Artificial Intelligence (December 1999). The papers in this book are extended versions of the original material published in the journal. They are organized into two categories: foundations and applications. Foundation papers present new ways of defining or analyzing invariants, andapplication papers present novel ways in which known invariant theory is extended and effectively applied to real-world problems in interesting and difficult contexts. Each category contains roughly half of the papers, but there is considerable overlap. All papers carry an element of novelty and generalization that will be useful to theoreticians and practitioners alike. It is hoped that this volume will be not only useful but also inspirational to researchers in image processing, pattern recognition and computer vision at large.

Download or read book Graphics Recognition Recent Advances written by Atul K. Chhabra and published by Springer. This book was released on 2014-03-12 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume contains refereed and improved versions of select papers 1 that were presented at the third IAPR Workshop on Graphics Recognition (GREC’99), held at Rambagh Palace in Jaipur, India, 26–27, September 1999. The workshop was organized by the TC10 (Technical Committee on Graphics Recognition) of the IAPR. Edited volumes from the previous two workshops in this series are also available as Lecture Notes in Computer Science (volumes 1072 and 1389). Graphics recognition is the study of techniques for computer interpretation of images of line drawings and symbols. This includes methods such as vectori- tion, symbol recognition, and table and chart recognition for applications such as engineering drawings, schematics, logic drawings, maps, diagrams, and musical scores. Some recently developed techniques include graphics-based information or drawing retrieval and recognition of online graphical strokes. With the recent advances in the ?eld, there is now a need to develop benchmarks for evaluating and comparing algorithms and systems. Graphics recognition is a growing ?eld of interest in the broader document image recognition community. The GREC’99 workshop was attended by ?fty-?ve people from ?fteen co- tries. The workshop program consisted of six technical sessions. Each session began with a half-hour invited talk which was followed by several short talks. Each session closed with a half-hour panel discussion where the authors ?elded questions from the other participants. Several interesting new research directions were discussed at the workshop.
