Enhanced Sliding-Mode Control For Permanent Magnet Synchronous Motor Servo Drive
A scheme for the speed control of permanentmagnet synchronous motor (PMSM), based on enhanced sliding-mode control (ESMC) algorithm, is proposed in this paper. The model of the PMSM based on field-oriented is given firstly. Then, the selection of proportional-plus-integral sliding surface (PISS) and a design approach of control law according to Lyapunov stability theory are discussed in detail. Meanwhile, in order to decrease the chatter, sliding mode control law is introduced a boundary layer near the sliding surface. Some simulation experiments have been made for examining the effectiveness of the proposed scheme. And the simulation results show that the method proposed in this paper represents accurate tracking and robust performance under the existence of uncertainties and external load disturbance.
