Permanent magnet synchronous motor has been widely used for its excellent performance. Aiming at the problem of unsatisfactory control results caused by the difficulty in parameter setting of dual closed-loop controllers, an improved double closed-loop PI controller based on pole configuration and Ramp function was proposed. From the perspective of the vector control algorithm of the permanent magnet synchronous motor, the system model of decoupling control with double closed-loop speed and current was established. In this model, the design methods of speed loop and current loop controller were discussed, and the calculation results of the parameters of the improved double loop controller were given. Computer simulations and practical tests were conducted on the research methods. The results showed that the optimized system reduced system overshoot, shortened the settling time, improved the dynamic response of the system, which indicated good engineering significance.

Key words: PMSM, vector control, pole placement, Ramp function, double closed-loop, PI
