摘要
针对传统的永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)采用比例-积分-微分(Proportion-Integral-Derivative,PID)控制器进行电流控制,在恶劣环境下电流波动较大、稳定性较差的问题,提出一种基于自抗扰理论的PMSM电流环控制算法。采用自抗扰控制器(Active Disturbances Rejection Controller,ADRC)取代PMSMq轴电流环的PID控制器,并在MATLAB/Simulink中搭建ADRC模型,进行建模仿真。结果表明,将自抗扰理论应用到PMSM电流环的控制算法中,PMSM的电流波动更小,运行更平稳。
Excessive current fluctuation and instability of PMSM（Permanent Magnet Synchronous Motor） with commonly used PID（Proportion-Integral-Derivative） controllers can be seen under adverse conditions. This paper develops a current loop control algorithm of PMSM where the PID controller of q axis is replaced by the ADRC（Active Disturbances Rejection Controller） controller and builds the model of the system based on ADRC with MATLAB/Simulink. The algorithm is verified through simulation.
