Abstract Traditional speed loop PI control of permanent magnet synchronous motor (PMSM) has poor speed tracking performance. Aiming at this problem, a compound PI controller is designed for the speed loop control system of surface PMSM (SPMSM). On the basis of traditional PI control, the integral clamping anti-integral saturation method is adopted in the speed loop, and the given input differential feedforward link and control gain link are added to enhance the tracking response performance of the speed loop system. The influence of the parameters of undamped natural frequency and damping ratio on the system's torque disturbance and angular speed measurement noise suppression ability is analyzed, which proves there is a contradiction between anti-torque disturbance and noise suppression performance of the system. For this reason, a new sliding mode observer (SMO) with speed as the state variable is designed to observe the motor speed, which is directly introduced into the closed-loop speed feedback system to avoid the influence of speed feedback noise on speed tracking performance. The experimental results verify the correctness of the theoretical analysis and the feasibility of the control strategy.
