Abstract

This paper proposes a method of detecting speed for the permanent magnet synchronous motor (PMSM) without speed sensors on the base of model reference adaptive system (MRAS) combining with variable structure control. Moreover, to weaken the chattering phenomenon coming from the signum function, a sigmoid function is utilized and an adaptive gain is designed. Meanwhile, a speed regulator is designed by the sliding mode technology to improve the dynamic performance of PMSM and to overcome drawbacks of the proportion integration differentiation (PID) controller. Simulation results are presented, which show the validity of this proposed strategy, and the desired effect can be obtained.
