Abstract :
An adaptive backstepping control for permanent magnet synchronous motor (PMSM) is presented in this paper. A non-linear backstepping controller was introduced in order to achieve high-performance speed tracking. That is robust to dynamic uncertainties and does not require knowledge of the electromechanical system parameters. In addition the controller can reject any bounded unmeasurable disturbances entering the system. Voltage level control inputs are designed using backstepping design methodology. A globally exponentially stable is proven by applying the Lyapunov stability theory. Simulation results are presented to illustrate the performances of the proposed controller under various conditions.
