Control Method of PMSM Based on Improved Sliding Mode Variable Structure
Permanent magnet synchronous motor (PMSM) has advantages of high efficiency,and energy saving,however,it is affected by many factors,and has the characteristics of complex changes.The traditional method has some problems,such as weak anti-interference ability,long system response time,poor stability and so on.In order to obtain the better control effect of PMSM,a new control method of PMSM by using improved sliding mode variable structure is proposed in this paper.The simulation experiment is carried out on Matlab 2014 and the results of the experiment are compared with those obtained by other methods.The results show that the proposed method can control the PMSM accurately,and the response time is short when load is in a mutation,and it has strong ability to resist the load disturbance and improve the dynamic performance of the system.The experimental results verify effectiveness and superiority of the proposed method in the control of permanent magnet synchronous motor.
