La commande vectorielle d'une machine asynchrone est une technique désormais arrivée à maturité. Cependant, les variateurs de vitesse industriels intègrent de nouvelles contraintes comme l'asservissement de vitesse sans codeur incrémental. Il est alors nécessaire d'avoir recours à des techniques d'observation au sens de l'automatique pour estimer la vitesse à partir des informations recueillies par la mesure des courants statoriques. Ainsi, on s'aperçoit que les disciplines de l'automatique et de l'électrotechnique se mêlent étroitement pour répondre à des exigences de plus en plus élevées. L'ouvrage est présenté sous forme d'exercices dont les solutions sont souvent très détaillées. Il s'adresse principalement à des élèves ingénieurs de la spécialité ou à des doctorants qui abordent le thème de la commande des machines.

This book describes the advances and applications in Sliding mode control (SMC) which is widely used as a powerful method to tackle uncertain nonlinear systems. The book is organized into 21 chapters which have been organised by the editors to reflect the various themes of sliding mode control. The book provides the reader with a broad range of material from first principles up to the current state of the art in the area of SMC and observation presented in a clear, matter-of-fact style. As such it is appropriate for graduate students with a basic knowledge of classical control theory and some knowledge of state-space methods and nonlinear systems. The resulting design procedures are emphasized using Matlab/Simulink software.

DANS CE TRAVAIL, L'AUTEUR PRESENTE UNE COMMANDE VECTORIELLE DESTINEE A UN VARIATEUR DE VITESSE D'UNE MACHINE ASYNCHRONE. LES CONTRAINTES DES APPLICATIONS INDUSTRIELLES NECESSITENT LA SUPPRESSION D'UN CAPTEUR MECANIQUE DE VITESSE OU DE POSITION. DANS CETTE LOGIQUE, UN ALGORITHME DE CONTROLE UTILISANT L'ESTIMATION DE LA VITESSE EST DEVELOPPE. LA MESURE DES COURANTS ET DES TENSIONS AUX BORNES DE LA MACHINE ASYNCHRONE SERT A LA RECONSTITUTION DE CETTE GRANDEUR MECANIQUE. LA PRIORITE POUR L'ELABORATION DE LA LOI DE COMMANDE A ETE SA SIMPLICITE. LES EQUATIONS ELECTRIQUES SONT LES SEULES UTILISEES POUR L'ESTIMATION DES GRANDEURS DE CONTROLE (FLUX, COUPLE, ET VITESSE). LA REGULATION DES COURANTS FOURNIS PAR UN ONDULEUR DE TENSION A M.L.I. PERMET UNE REDUCTION A 2 DE L'ORDRE DU MODELE DE LA MACHINE. CE MODELE EST CARACTERISE PAR UN FORT COUPLAGE ENTRE LES COMPOSANTES DE FLUX ET LA VITESSE. UN OBSERVATEUR D'ORDRE REDUIT, ETABLI SUR UN MODELE VOISIN DE LUENBERGER, ASSURE LA CONNAISSANCE DES COMPOSANTES DU FLUX ROTORIQUE DANS UN REPERE FIXE LIE AU STATOR. LA VITESSE EST ESTIMEE A PARTIR DE CES COMPOSANTES DE FLUX ET DES COMPOSANTES DU COURANT STATORIQUE. CES ESTIMATIONS SONT UTILISEES POUR LE CONTROLE EN CHAMP ORIENTE DIRECT. L'ENSEMBLE DU CONTROLE EST ANALYSE PAR SIMULATION. DEUX MAQUETTES EXPERIMENTALES SONT REALISEES, DANS LESQUELLES L'ALGORITHME EST IMPLANTE SUR UN PROCESSEUR RAPIDE DSP A STRUCTURE RISC. LES RESULTATS EXPERIMENTAUX OBTENUS A DIVERS POINTS DE FONCTIONNEMENT CONFIRMENT UN COMPORTEMENT SATISFAISANT DE L'ENSEMBLE DE L'ENTRAINEMENT. CEPENDANT, CETTE ETUDE A MIS EN EVIDENCE LE ROLE CRITIQUE DES MESURES DE TENSION UTILISEES DANS L'OBSERVATEUR D'ORDRE REDUIT

This book addresses a range of real-world issues including industrial activity, energy management, education, business and health. Today, technology is a part of virtually every human activity, and is used to support, monitor and manage equipment, facilities, commodities, industry, business, and individuals’ health, among others. As technology evolves, new applications, methods and techniques arise, while at the same time citizens’ expectations from technology continue to grow. In order to meet the nearly insatiable demand for new applications, better performance and higher reliability, trustworthiness, security, and power consumption efficiency, engineers must deliver smart innovations, i.e., must develop the best techniques, technologies and services in a way that respects human beings and the environment. With that goal in mind, the key topics addressed in this book are: smart technologies and artificial intelligence, green energy systems, aerospace engineering/robotics and IT, information security and mobile engineering, IT in bio-medical engineering and smart agronomy, smart marketing, management and tourism policy, technology and education, and hydrogen and fuel-cell energy technologies.

The induction motor is one of the most significant innovations in contemporary history and it officially kicked off the Second Industrial Revolution by significantly enhancing energy generation efficiency. Induction motors are utilized in a wide variety of applications in the modern industrial world. Motivated by the importance of recent advances, new perspectives, and applications of induction motors, this book presents research from distinguished experts in the field. It addresses recent advances in induction motors, optimal solutions in field-oriented control, the association of converters to induction motors, dynamic analysis, optimized design of synergetic control, fault-tolerant control, mathematical modeling, an adaptive system scheme for a sensorless drive, modeling, and simulation of a system with inter-turn faults, sensorless speed observer for industrial drives, and induction motor applications in electric vehicles. This book is useful for undergraduates, graduate students, researchers, professors, and field engineers due to its combination of both theoretical coverage and real-world application concepts.

Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park’s transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in industry. Both, conventional control strategies like vector control (either in the synchronous reference frame or in the rotor frame) and advanced control theories like direct control and predictive control are thoroughly presented. In this context, a significant place is reserved to sensorless control which is an important and critical issue in tomorrow’s motors.

La connaissance du comportement transitoire de la machine asynchrone est souvent nécessaire pour déterminer la performance globale de l'ensemble du système, auquel la machine appartient. L'approche proposée dans ce livre consiste à introduire deux phénomènes magnétiques à savoir: la saturation et les pertes fer. Après avoir analysé le comportement dynamique de la machine, différentes lois de commande vectorielle ont été étudiées. Elles ont pour objectif d'éliminer les couplages électriques apparaissant dans le système provoqués par la saturation et les pertes fer et d'obtenir de meilleures performances. L'élimination du capteur mécanique dans une commande vectorielle a été analysée. Un modèle de type MRAS pour l'estimation de la vitesse a été développé de telle sorte que la saturation et les pertes fer soient compensées particulièrement en fonctionnement en mode défluxé. Ensuite, cet estimateur est substitué par un autre insensible aux variations paramétriques et basé sur l'intelligence artificielle. L'implantation de ces méthodes et la validité des modèles ont été testées sur un dispositif expérimental, muni d'une carte de commande dSPACE de type DS1104.
