Available in PDF, EPUB and Kindle. Book excerpt: LE TRAVAIL PRESENTE CI-APRES S'INTERESSE A LA COMMANDE DES CONVERTISSEURS STATIQUES ET APPORTE UNE CONTRIBUTION A LA DEFINITION DES LOIS DE COMMUTATION A L'AIDE DE LA THEORIE DES REGIMES GLISSANTS BASEE SUR UNE FONCTION DE LYAPUNOV. LA PREMIERE PARTIE DE CE TRAVAIL EST CONSACREE A L'ETUDE DE LA THEORIE DES REGIMES GLISSANTS EN VUE DE L'APPLICATION A LA COMMANDE DES CONVERTISSEURS STATIQUES. L'AUTEUR PROPOSE UNE NOUVELLE METHODE POUR LA DEFINITION DE SURFACES DE COMMUTATION QUI PERMET D'ASSURER LA STABILITE ET L'EXISTENCE GLOBALE D'UN REGIME GLISSANT POUR DES CONVERTISSEURS COMPRENANT UNE OU PLUSIEURS CELLULES DE COMMUTATION. LA DEUXIEME PARTIE TRAITE DE L'APPLICATION A DIFFERENTES STRUCTURES DE CONVERTISSEURS. UNE REALISATION EXPERIMENTALE D'UNE PUISSANCE DE 10KW A PERMIS DE VALIDER LA LOI DE COMMANDE DEVELOPPEE EN FONCTIONNEMENT HACHEUR ET ONDULEUR D'UN CONVERTISSEUR ABAISSEUR DE TENSION. CE TRAVAIL APPORTE DES SOLUTIONS POUR LE FONCTIONNEMENT A FREQUENCE FIXE ET LA STABILITE DE D'ENSEMBLE CONVERTISSEUR-FILTRE D'ENTREE. UNE ETUDE AVEC VALIDATION PAR SIMULATION EST MENEE SUR LA COMMANDE PAR MODE DE GLISSEMENT D'UN HACHEUR SURVOLTEUR ET D'UN CONVERTISSEUR MULTINIVEAUX A CELLULES DE COMMUTATIONS IMBRIQUEES. IL S'AVERE QUE LA THEORIE DES REGIMES GLISSANTS SE GENERALISE PARFAITEMENT A LA COMMANDE DES STRUCTURES COMPLEXES DE TYPE NON-LINEAIRE ET MULTI-ENTREE. CE TRAVAIL MONTRE QUE LES PRINCIPES DU REGLAGE PAR MODE DE GLISSEMENT PEUVENT ETRE AVANTAGEUSEMENT UTILISES POUR LA COMMANDE DES CONVERTISSEURS STATIQUES. LA ROBUSTESSE VIS-A-VIS DES VARIATIONS DE PARAMETRES ET LA SIMPLICITE DE LA MISE EN UVRE CONSTITUENT LES ATOUTS DE CETTE STRATEGIE DE COMMANDE. CONTRAIREMENT A UNE LOI DE COMMANDE CLASSIQUE, LES PERFORMANCES DYNAMIQUES NE DEPENDENT PAS D'UN POINT DE FONCTIONNEMENT NOMINAL MAIS SONT IMPOSEES DANS TOUTE LA PLAGE DE FONCTIONNEMENT DU CONVERTISSEUR
Book Synopsis Contribution à la commande floue d'un convertisseur statique by : Kamel Guesmi
Download or read book Contribution à la commande floue d'un convertisseur statique written by Kamel Guesmi and published by . This book was released on 2006 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les convertisseurs statiques sont des systèmes électroniques caractérisés par la commutation cyclique entres les configurations du circuit. Malgré leur simplicité, ils présentent une variété de comportements non linéaires. Ceci rend l'analyse et la prédiction du comportement du système dificile. Pour étudier ces comportements, les techniques de la modélisation discrète utilisent des hypothèses et des contraintes sur les modes de fonctionnement et de commande du système pour simplifier la tâche de modélisation. Dans cette thèse nous avons proposé d'introduire quelques améliorations sur la modélisation discrète afin de mieux décrire le comportement du système sans aucune contrainte ou hypothèse simplificatrice. Les contrôleurs développés pour le convertisseur sont basés, généralement, sur son modèle mathématique, donc les variations larges des paramètres du convertisseur peuvent altérer les performances de contrôle. La logique flou est un des systèmes du contrôle où leurs paramèters peuvent varier en fonction du changement des paramètres du système. De ce fait, nous avons proposé une approche systématique pour la synthèse du contrôleur flou stabilisant afin de supprimer les phénomènes anormaux exhibés par le convertisseur et maintenir les performances de la régulation dans un grand intervalle de variation des paramètres du système.

Book Synopsis Electrical Machine Analysis Using Finite Elements by : Nicola Bianchi
Download or read book Electrical Machine Analysis Using Finite Elements written by Nicola Bianchi and published by CRC Press. This book was released on 2017-12-19 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the fan motor in your PC to precision control of aircraft, electrical machines of all sizes, varieties, and levels of complexity permeate our world. Some are very simple, while others require exacting and application-specific design. Electrical Machine Analysis Using Finite Elements provides the tools necessary for the analysis and design of any type of electrical machine by integrating mathematical/numerical techniques with analytical and design methodologies. Building successively from simple to complex analyses, this book leads you step-by-step through the procedures and illustrates their implementation with examples of both traditional and innovative machines. Although the examples are of specific devices, they demonstrate how the procedures apply to any type of electrical machine, introducing a preliminary theory followed by various considerations for the unique circumstance. The author presents the mathematical background underlying the analysis, but emphasizes application of the techniques, common strategies, and obtained results. He also supplies codes for simple algorithms and reveals analytical methodologies that universally apply to any software program. With step-by-step coverage of the fundamentals and common procedures, Electrical Machine Analysis Using Finite Elements offers a superior analytical framework that allows you to adapt to any electrical machine, to any software platform, and to any specific requirements that you may encounter.

Book Synopsis Analysis of Electrical Machines by : Valeria Hrabovcova
Download or read book Analysis of Electrical Machines written by Valeria Hrabovcova and published by BoD – Books on Demand. This book was released on 2020-05-20 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to students, PhD students, postgraduates of electrical engineering, researchers, and scientists dealing with the analysis, design, and optimization of electrical machine properties. The purpose is to present methods used for the analysis of transients and steady-state conditions. In three chapters the following methods are presented: (1) a method in which the parameters (resistances and inductances) are calculated on the basis of geometrical dimensions and material properties made in the design process, (2) a method of general theory of electrical machines, in which the transients are investigated in two perpendicular axes, and (3) FEM, which is a mathematical method applied to electrical machines to investigate many of their properties.

Book Synopsis Formal Methods Applied to Complex Systems by : Jean-Louis Boulanger
Download or read book Formal Methods Applied to Complex Systems written by Jean-Louis Boulanger and published by John Wiley & Sons. This book was released on 2014-07-22 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents real-world examples of formal techniques in an industrial context. It covers formal methods such as SCADE and/or the B Method, in various fields such as railways, aeronautics, and the automotive industry. The purpose of this book is to present a summary of experience on the use of “formal methods” (based on formal techniques such as proof, abstract interpretation and model-checking) in industrial examples of complex systems, based on the experience of people currently involved in the creation and assessment of safety critical system software. The involvement of people from within the industry allows the authors to avoid the usual confidentiality problems which can arise and thus enables them to supply new useful information (photos, architecture plans, real examples, etc.).
