This paper introduces a speed control of permanent magnet synchronous motor based on adaptive PID algorithm, and proposes a simplified self-adaptive strategy to carry out online self-correction of PID parameters. Compared with traditional PID controller, the controller enhances its response performance to nonlinear, time-varying and disturbance of motor. Moreover, the adaptive strategy is with a simple structure, easy to implement in engineering, and has a certain practical value in engineering. The simulation results show that compared with the traditional PID control, the response transition time is shorter and the overshoot is smaller.
