摘　　要：为抑制同步磁阻电机的转矩脉动并提高系统的鲁棒性,文中提出了一种基于多谐振速度环控制与自抗扰电流环的复合控制策略。由于同步磁阻电机的磁阻变化不均匀,从而导致电机电感随着磁饱和与交叉耦合效应变化,一方面,电感参数的变化会给电流环控制带来影响;另一方面,电感参数的变化还会引起转矩的脉动。因此提出基于多比例谐振的速度环控制策略,以抑制同步磁阻电机的转矩谐波。基于超局部模型的无差拍电流预测控制,利用改进的锁相环观测器对下一拍的电流和扰动进行预测,在电机参数变化时可以很好地实现电流的跟踪,从而提高系统的抗干扰能力。To suppress the torque ripple of synchronous reluctance motor(SynRM)and improve the robustness of the system,a compound control strategy based on multiple resonant velocity loop control and active disturbance rejection current loop is proposed.Because the reluctance of SynRM is not uniform,the inductance of the motor changes with the magnetic saturation and cross-coupling effect.On the one hand,the inductance parameter changes will affect the current loop control.On the other hand,the change of inductance parameter will cause torque pulsation;Therefore,a speed loop control strategy based on multi-proportional resonance is proposed to suppress the torque harmonics of SynRM.The beat free current predictive control based on the hyperlocal model uses the improved phase-locked loop observer to predict the current and disturbance of the next beat,which can track the current well when the motor parameters change,thus improving the anti-interference ability of the system.
