THE PERMANENT MAGNET SYNCHRONOUS MOTOR ROBUST NONLINEAR FEEDBACK CONTROL BASED ON LYAPUNOV METHOD -EXPERIMENTAL EVALUATION-

Abstract

This paper deals with a robust control intended for permanent magnet synchronous motor. Two approaches are used: the first one a nonlinear input output state feedback linearizing control and second one is a proposed nonlinear feedback control based on Lyapunov method. This second solution shows good robustness with respect to parameter variations, measurement errors and noises. Finally, simulation and experimental results are given to demonstrate the effectiveness and the good performance of the proposed control.
