In view of the load torque disturbance effect on the control of the permanent magnet synchronous motor (PMSM)，an active disturbance rejection control (ADRC) strategy for PMSM based on feedforward compensation is proposed. The linear active disturbancerejection control (LADRC) is used to improve the contradiction between the rapidity and overshoot of the traditional PID controller, and the load torque feedforward compensation method is introduced. The torque observed by the load torque observer feeds back to the current loop in proportion when the load torque changes suddenly. The simulation results show that the control effect of the LADRC system with feedforward compensation is obviously optimized for the PMSM, and the speed fluctuation caused by the sudden load torque is effectively suppressed, which verifies the effectiveness of the strategy.
