针对负载转矩扰动对永磁同步电机(PMSM)控制造成的影响，提出了一种基于前馈补偿的PMSM自抗扰控制(ADRC)策略。通过线性自抗扰控制(LADRC)改进传统PID控制器快速性和超调之间的矛盾，并且通过引入负载转矩前馈补偿的方法，将负载转矩观测器观测到的转矩按比例反馈到电流环中，在负载转矩发生突变时进行补偿。仿真结果表明，增加了前馈补偿的LADRC系统对PMSM的控制效果明显优化，有效地抑制了因负载转矩突变引起的转速波动，验证了所提策略的有效性。

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.
