摘　　要：为提高伺服系统的控制性能并解决控制参数整定困难的问题,该文设计了1种新的控制方法,应用于永磁同步电机(PMSM)伺服控制系统中。建立了PMSM模型。设计了基于电流环带宽进行比例-积分(PI)控制参数整定的电流环控制器和基于速度环带宽进行自抗扰控制(ADRC)参数整定的速度环控制器。推导得到电流环带宽和速度环带宽的关系,从而将整个系统的控制参数归结到带宽1个参数上。经实验验证:该控制器结构通用性强,参数整定简单,易于工程实现;与传统比例-积分-微分(PID)控制方法相比较,在给定相同速度指令时,基于带宽的控制方法速度响应快,跟踪误差减小40%以上,在PMSM速度稳定时施加负载扰动,稳定时间缩短25%以上。In order to improve the control performance of servo systems and solve the difficulty of setting control parameters,a new control method is designed and applied to the servo control system of a permanent magnet synchronous motor(PMSM).The model of the PMSM is established.A current loop controller is designed with proportional-integral(PI)control parameters tuning based on the current loop bandwidth,and a speed loop controller is designed with active disturbance rejection control(ADRC)parameters tuning based on the speed loop bandwidth.The relationship between the current loop bandwidth and the speed loop bandwidth is given,and the control parameters of the whole system are reduced to a bandwidth.The result of a physical test verifies that this controller has strong structure versatility,simple parameter setting and easy engineering implementation;compared with the traditional proportional-integral-derivative(PID)control method,under a same speed instruction,the response of the control method based on bandwidth is faster,and the tracking error is reduced by more than 40%,and the stabilization time is shortened by more than 25%for a load disturbance on a PMSM operating steadily.
