Available in PDF, EPUB and Kindle. Book excerpt: L'ouvrage présente une approche didactique de la conception d'une commande robuste en s'appuyant sur de nombreux exemples pertinents. Il s'articule en neuf chapitres constituant quatre parties : La première partie regroupe des rappels sur la transformée en z, la stabilité, les notions d'asservissement et de régulation. La seconde partie présente une méthodologie de réglage basée sur un placement de pôles. des correcteurs de type 'PID' en temps continu et échantillonné. Ensuite, un chapitre sur la méthodologie de conception robuste, d'une commande en présence de perturbations, constitue un point original de l'approche proposée. Enfin, la dernière partie décrit une généralisation du placement de pôles vu pour les correcteurs de type PID. la commande par modèle interne et la commande polynomiale RST. Chaque chapitre comprend de nombreux exemples tirés de problématiques industrielles pour illustrer l'approche robuste envisagée. Conçu pour des étudiants de second cycle, l'ouvrage sera également précieux pour les ingénieurs et techniciens, désireux de parfaire leurs connaissances en automatique avec une approche encore peu pratiquée en milieu industriel.
Download or read book La commande robuste par loop shaping written by FEYEL Philippe and published by Lavoisier. This book was released on 2013-07-01 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’approche loop-shaping consiste en l’obtention d’une spécification relative à la boucle ouverte de l’asservissement à partir de spécifications relatives à divers transferts en boucle fermée. Parce qu’il est plus simple de travailler sur un unique transfert (la boucle ouverte) plutôt que sur une multitude de transferts bouclés, cette approche s’avère particulièrement adaptée au contexte industriel. Cet ouvrage se concentre sur la déclinaison des spécifications de haut niveau vers une spécification de type loop-shaping, puis sur les techniques permettant d’intégrer pleinement cette démarche pour le calcul de correcteurs robustes et performants, en particulier par la synthèse H?. Modelage de la boucle ouverte escomptée, la synthèse H? par loop-shaping permet par ailleurs de stabiliser toute une boule de modèles grâce à la notion de gap métrique, ce qui s’avère particulièrement intéressant pour la prise en compte de contraintes industrielles. La volonté accrue de réaliser des asservissements à moindre coût et de plus en plus performants mène à l’optimisation de cette technique, la rendant indispensable à son domaine.

Available in PDF, EPUB and Kindle. Book excerpt: Pour représenter au mieux le fonctionnement dynamique d'un processus, une approche globale basée sur de multiples modèles LTI (linéaires ou affines) autour de différents points de fonctionnement est utilisée. Cette approche multimodèle est une représentation polytopique convexe pouvant être obtenue, soit directement à partir d'un modèle mathématique non linéaire, soit par transformation mathématique, soit par linéarisation autour de différents points de fonctionnement. Basé essentiellement sur la deuxième méthode de Lyapunov et la formulation LMI, Multimodèles en automatique se concentre sur l'analyse de la stabilité et la synthèse de correcteurs/observateurs. Le cas des multimodèles incertains avec des entrées inconnues est étudié et les fonctions de Lyapunov quadratiques et non quadratiques sont également considérées. Afin de réduire le pessimisme de la méthode quadratique, l'étude de stabilité des multimodèles est réalisée en considérant des fonctions de Lyapunov non quadratiques.
Download or read book Command control for Real time Systems written by Mohammed Chadli and published by John Wiley & Sons. This book was released on 2013-04-25 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: A real-time system is a complex system which is an integral part of an industrial or experimental system, a vehicle or a construction machine. The peculiarity of these systems is that they are driven by real-time targets in distributed environments. Command-control for Real-time Systems presents the calculation of correction for industrial systems of different physical natures, their implementation on real-time target industrial systems (PLC-SCADA, embedded systems with distributed networks, Networked Control Systems) and their validation by simulation. It optimizes industrial processes by the use of automatic tools, industrial computing and communications networks and aims to successively integrate new control laws (linear, nonlinear and fuzzy controllers) so that users can leverage the power of engineering science as an automatic service process optimization while maintaining their high maintainability facilities.

Available in PDF, EPUB and Kindle. Book excerpt: In the last two decades, fractional (or non integer) differentiation has played a very important role in various fields such as mechanics, electricity, chemistry, biology, economics, control theory and signal and image processing. For example, in the last three fields, some important considerations such as modelling, curve fitting, filtering, pattern recognition, edge detection, identification, stability, controllability, observability and robustness are now linked to long-range dependence phenomena. Similar progress has been made in other fields listed here. The scope of the book is thus to present the state of the art in the study of fractional systems and the application of fractional differentiation. As this volume covers recent applications of fractional calculus, it will be of interest to engineers, scientists, and applied mathematicians.

Download or read book La synth se H infini en pratique written by Gilles Duc and published by . This book was released on 2022-01-05 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: La synthèse H-infini, qui a émergé dans les années 1990, est un ensemble deméthodes souples et efficaces pour concevoir des lois de commande assurant de bons niveaux de performance et de robustesse aux incertitudes de modélisation. Mais si la théorie est maintenant bien connue, ce n'est pas le cas pour le cheminement permettant d'en tirer parti pour concevoir des commandes optimales. Cet ouvrage, destiné aux ingénieurs en automatique et en régulation, vise à combler cette lacune, en rappelant le minimum de bases mathématiques nécessaire mais surtout en expliquant en détails comment utiliser cette méthode, en s'appuyant sur de nombreux cas d'application issus de l'aéronautique, de l'automobile ou encore de la robotique.

Available in PDF, EPUB and Kindle. Book excerpt: Porte sur la commande robuste aux incertitudes paramétriques, des moteurs asynchrones. Notre première approche consiste à réaliser une commande vectorielle par orientation du flux rotorique utilisant des termes de compensations afin de découpler et linéariser les transferts tensions/courants. La pulsation statorique est, quant à elle, calculée par autopilotage à l'aide de la pulsation mécanique et de la pulsation de glissement déduit des équations du moteur asynchrone. La robustesse des boucles de régulations de courants est assurée par des correcteurs HÆ mono-entrée mono-sortie utilisant une méthode simple et efficace de conception. La commande a été améliorée par l'utilisation d'un observateur de Kalman réduit à état retardé, étendu à deux paramètres de la machine. Notre seconde approche réalise la suppression des termes de compensations et de l'autopilotage. Après une analyse modale mettant en évidence les couplages, nous avons réalisé la synthèse d'un correcteur dynamique multi-entrées multi-sorties, de façon à réguler les flux et le couple. La robustesse est assurée par placement de structure propre lors de la synthèse du correcteur modale (découplage, minimisation des variations). Enfin, chaque méthode mise au point a été validée sur un banc d'essai composé d'un moteur 5.5Kw et d'un onduleur 10Kw.
