Abstract：According to two different control method of variable frequency speed control for permanent magnet synchronous motor,this paper presents a variable frequency speed control method based on the combination of other-control and self-control. The method combines the characteristics of other-control variable frequency speed control with high precision and self-control variable frequency speed control without out of step, and improves the dynamic and steady state performance of the control system. The simulation model of automatic switching between control method is established on the Matlab/Simulink platform. The simulation experimental results show that the method is effective and feasible.
