Commande par mode de glissement d’ordre supérieur de la machine synchrone à aimants permanents

Abstract

This thesis, presents a study the modeling and control of the permanent magnet synchronous machine (PMSM) fed by a voltage inverter controlled by space vector modulation. Field oriented control of the PMSM, using PI controllers presents some disadvantages such as the sensitivity to parametric uncertainties of the machine and their variations. In order to improve the system performances, we applied robust control techniques such as : classical sliding mode control, second order sliding mode control (Super Twisting Algorithm). This later is characterized by its tracking precision and the important reduction of the chattering. The obtained simulation results, showed the effectiveness and the performances of the proposed control technique.
