| Abstract: | les machines multiphasées occupent une place croissante dans les applications industrielles de forte puissance. Ce mémoire porte sur la commande vectorielle directe d’une structure innovante composée d’une machine asynchrone à double étoile (MASDE), alimentée par deux onduleurs à deux niveaux commandés par MLI. La simulation du système, intégrant la machine, son alimentation ainsi que la commande par orientation du flux rotorique à l’aide de régulateurs PI classiques, met en évidence l’efficacité de cette approche. Toutefois, les tests de robustesse révèlent certaines limites de ces régulateurs, notamment leur sensibilité aux variations des paramètres de la machine. تشغل الآلات متعددة الطور مكانة متزايدة في التطبيقات الصناعية عالية القدرة. يتناول هذا البحث التحكم الاتجاهي المباشر في هيكل مبتكر يتكون من آلة غير متزامنة مزدوجة النجوم (MASDE)، تغذى بواسطة عاكسين ثنائيي المستويات يتم التحكم فيهما بواسطة MLI. تحاكي النظام، بما في ذلك الآلة، وتغذيتها، وكذلك التحكم بتوجيه التدفق الدوار باستخدام منظمات PI التقليدية، مما يبرز فعالية هذا النهج. ومع ذلك، تكشف اختبارات المتانة عن بعض حدود هذه المنظمات، لا سيما حساسيتها لتغيرات معلمات الآلة. Multiphasic machines are increasingly occupying a place in high-power industrial applications. This thesis focuses on the direct vector control of an innovative structure composed of a double-star asynchronous machine (MASDE), powered by two two-level inverters controlled by PWM. The simulation of the system, integrating the machine, its power supply, and the control by rotor flux orientation using classical PI regulators, highlights the effectiveness of this approach. However, robustness tests reveal certain limitations of these regulators, particularly their sensitivity to variations in the machine's parameters.
