Abstract
This paper is devoted to the study of the performances of a robust speed nonlinear control of five-phase permanent magnet synchronous motor (PMSM).The dynamic response speed and overshoot is contradictory and the system is weak in terms of anti-interference in classical PI speed regulator. In this work, the controllers are designed using two methods: the first one using a nonlinear control based on sliding mode control (SMC). In the second, the super twisting algorithm sliding mode speed control (STSMC) is used to overcome the occurring chattering phenomena. This second solution shows good robustness with respect to parameter variations, measurement errors and noises. Finally, simulation results are given to demonstrate the effectiveness and the good performance of the proposed control methods.
