L'objectif de ce travail est le développement d'une structure d'observation des variables de commande du Contrôle Direct du Couple (DTC) d'une machine asynchrone. Cette structure doit résoudre un dilemne de robustesse et de temps de calcul minimal. La loi de commande obtenue sera utilisée pour la commande multimachines-multiconvertisseurs. Dans ce mémoire, l'auteur a tout d'abord étudié les nouvelles lois de commande dites à contrôle direct du flux statorique et du couple électromagnétique, en particulier le DTC et ceci en montrant les principes du réglage du flux, du couple et la définition de la logique de commutation. Ensuite il a développé trois structures d'observation : l'observateur d'état d'ordre complet, l'observateur à modes glissants et l'observateur découplé. Une étude comparative entre ces trois structures ainsi que l'estimateur classique, montre que l'observateur découplé est une structure intéressante qui répond aux contraines temporelles liées au DTC et qui résout le problème de fonctionnement à très basses vitesses. Pour l'application multimachines, l'auteur a étudié deux systèmes : le système monoondulateur-bimachines et le système biondulateur-bimachines. La commande est effectuée avec le DTC et le contrôle vectoriel. Comme pour le contrôle vectoriel, le DTC donne des résultats intéressants pour la commande des systèmes multimachines. La dernière partie de ce mémoire consiste à définir une architecture matérielle de validation en mono et multimachines. Il s'agit d'une validation pseudo-expérimentale, de la loi de commande associée à la structure d'observation développée. Ceci est effectué par une co-simulation mixte analogique/numérique.

This book includes the latest research presented at the International Conference on Artificial Intelligence in Renewable Energetic Systems held in Tipaza, Algeria on October 22–24, 2017. The development of renewable energy at low cost must necessarily involve the intelligent optimization of energy flows and the intelligent balancing of production, consumption and energy storage. Intelligence is distributed at all levels and allows information to be processed to optimize energy flows according to constraints. This thematic is shaping the outlines of future economies of and offers the possibility of transforming society. Taking advantage of the growing power of the microprocessor makes the complexity of renewable energy systems accessible, especially since the algorithms of artificial intelligence make it possible to take relevant decisions or even reveal unsuspected trends in the management and optimization of renewable energy flows. The book enables those working on energy systems and those dealing with models of artificial intelligence to combine their knowledge and their intellectual potential for the benefit of the scientific community and humanity.

Cette thèse de doctorat décrit la conception et la mise en oeuvre d'une commande directe du couple d'une machine asynchrone triphasée. L'alimentation est assurée par un onduleur de tension à deux niveaux. Pour la stratégie de commande directe du couple, deux variantes de contrôle sont étudiées : La première est basée sur le contrôle direct du couple (CDC), dont les commutations de l'onduleur sont obtenues à partir de l'information de sortie des deux contrôleurs à hystérésis (couple, flux) et la position du flux statorique. La deuxième concerne le contrôle direct du couple prédictif (CDCP) basé sur le modèle de la machine asynchrone, dont les différentes commutations de l'onduleur sont obtenues à partir de la prédiction des futures valeurs des variables contrôlées (couple, flux) et l'optimisation de leurs erreurs par l'entremise d'une fonction de coût prédéfinie auparavant. La reconstitution des valeurs fondamentales de contrôle (courant, flux) est assurée par un filtre de Kalman de quatrième ordre pour faciliter l'intégration de la commande dans le contexte de contrôle direct du couple. D'autre part, un estimateur de perturbations muni d'un schéma antidépassement a aussi été étudié et intégré, dans le contrôle prédictif de la vitesse en boucle fermée adopté pour cette étude. La deuxième variante a mené à une amélioration par rapport aux résultats de la variante classique, en particulier dans la réduction de taux d'ondulation du couple et du flux statorique. Elle a aussi montré une performance dynamique appréciable, notamment enmatière de rejection des perturbations et de robustesse vis-à-vis de couple de charge sur une large plage de vitesse. En résumé, nos contributions scientifiques sont : 1- La mise en oeuvre d'une nouvelle stratégie de contrôle direct de couple prédictif basé sur le modèle de la machine asynchrone triphasée. 2- L'implementation expérimentale des deux structures de commande (« CDC » et « CDCP ») sur le système de prototypage rapide OPAL-RT disponible au sein du laboratoire LICOME de l'Université du Québec à Chicoutimi. Cette thèse débouche sur la réalisation d'un prototype, avec l''implémentation temps réel des deux variantes de contrôle directe du couple sur la plateforme OPAL-RT. Les résultats expérimentaux obtenus montrent de bonnes performances statiques et dynamiques et confirment les résultats de simulations obtenus sous l'environnement Matlab/Simulink. In this thesis, design and development of direct torque controlled three-phase induction motor drive is presented. The induction machine is fed from a two level inverter. The control of the drive is realized using two direct torque control strategies as given below: The first strategy is based on classical method DTC wherein the control signals for the inverter power devices are obtained using the output data from two hysteresis controllers and stator flux position. The second control strategy is a predictive method PDTC based on the model of the machine wherein the inverter switching signals are obtained by predicting future values of control variables (torque and stator flux) and optimizing their errors via a predefined costfunction. Reconstruction of control variables (current and flux) for controls is assured using a four order Kalman Filter. On the other hand, a disturbance observer with an anti-overflow scheme has also been studied and incorporated in the predictive closed-loop speed control adopted for this study. The second strategy has led to an improvement in the results of the classical method, especially in reducing torque ripple and stator flux. It also showed a significant improvement in dynamic performance, especially in terms of disturbance rejection and robustness over a wide speed range. This work leads to the development of a prototype, with real-time implementation of two controls (CDC and CDCP) variants via RT-LAB platform available in the LICOME laboratory of the University of Quebec at Chicoutimi. The experimental results show good transient and steady state performance and confirm the simulation results obtained using Matlab/Simulink.

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.
