SLIDING MODE CONTROLLER BASED ON FUZZY LOGIC FOR PMSM SERVO SYSTEM WITH UNCERTAIN DISTURBANCE

Abstract

This paper introduces the model of PMSM (permanent magnet synchronous
motor) motor system with uncertain noise components. Since then, designing a
sliding controller with constraints from fuzzy rules helps the system move to the
sliding domain faster, minimizing chattering. The stability of the controller is
proven according to Lyapunov standard and verified by simulation by
Matlab/Simulink software. The results demonstrated that the proposed controller
gives better performance in both current and speed for the PMSM drive system.
