摘　　要：针对永磁同步电机(PMSM)双环伺服控制系统中存在动态响应慢和抗干扰性能差的问题,提出了一种基于扰动观测器的分数阶协同转速控制器代替传统PI控制器,将扰动观测器中传统的符号函数取代为反正切三角函数,采用基于非线性误差函数的分数阶流形代替传统积分流形。同时,为了解决电流环采用PI控制器时电流波动较大的问题,采用两个基于分数阶协同控制的电流控制器分别控制d、q轴上的电流;最后根据PMSM系统控制框图搭建仿真模型并进行仿真,分别对转速环控制策略和电流环控制策略进行对比。实验结果表明,采用基于分数阶协同控制的PMSM双环伺服系统可以提高系统电流控制性能,具有更好的抗干扰性能。Aiming at the problems of slow dynamic response and poor anti-interference performance in the double-loop servo control system of permanent magnet synchronous motor(PMSM),a fractional order synergetic speed controller based on disturbance observer is proposed to replace the traditional PI controller.In this paper,the traditional symbolic function is replaced by the arctangent trigonometric function,and the fractional manifold based on the nonlinear error function is used to replace the traditional integral manifold.At the same time,in order to solve the problem of large current fluctuations when the current loop adopts the PI controller,this paper uses two current controllers based on fractional order synergetic control to control the current on the d and q axis respectively;finally,a simulation model is built according to the control block diagram of the PMSM system.The simulation is carried out,and the speed loop control strategy and the current loop control strategy are compared respectively.The experimental results show that the PMSM double-loop servo system based on fractional order synergetic control can improve the current control performance of the system and have better anti-interference performance.
