Etude comparative entre la régulation vectorielle et Mode glissant pour un moteur synchrone a aimant permanant

Abstract

This paper presents a modeling and control study of a synchronous machine with permanent magnets fed by an inverter controlled by an electric current. The radial modulation strategy, the method of controlling the flow direction using the traditional regulator is characterized by several disadvantages such as sensitivity For frequencies and changes of machine variable. That's why we have implemented a powerful technique such as: this last sliding pattern is characterized by accuracy of follow and the significant reduction of vibrations. The obtained simulation results proved the effectiveness and quality of the proposed control technique.
