摘　　要：针对永磁同步电机速度控制中存在超调量大,抗负载扰动能力差,采用负载转矩补偿和自抗扰相控制结合的方案,给出一种改进的自抗扰补偿方式,不仅可以发挥经典自抗扰的优点,同时也对负载扰动进行补偿。通过对所给方法的仿真和试验结果分析可得,与传统的PID控制器相比,改进的线性自抗扰补偿控制系统具有较小的超调和稳态误差、较快的响应速度等性能,同时具有好的抗负载扰动能力,提升永磁同步电机的鲁棒性的同时使得动态性能与静态性能也提高很多。Aiming at the large overshoot in the speed control of permanent magnet synchronous motor(PMSM)and the poor ability of anti-load disturbance,a scheme combining load torque compensation and ADRC was adopted to present an improved auto-disturbance rejection method.It can not only exert the advantages of classical auto-disturbance rejection,but also compensate the load disturbance.Through the simulation and experimental results obtained by the given method it shows that compared with the traditional PID controller,the improved linear ADRC system has the characteristics of smaller overshoot and steady-state error,faster response speed and better anti-load disturbance ability.In the meantime of robustness improvement of PMSM,the dynamic and static performances are also increased a lot.
