Adaptive control of a synchronous motor via a sliding mode decomposition technique

This paper presents a decoupled control strategy using time-varying sliding surface-based sliding-mode controller for speed control of permanent magnet synchronous motor (PMSM). The decoupled method provides a simple way to achieve asymptotic stability for a PMSM by dividing the system into two subsystems electrical and mechanical systems. The simulation results for PMSM are presented to demonstrate the effectiveness and robustness of the method. Comparing this controller with pulse width modulation (PWM) controller for the same motor.
