基于变论域模糊自抗扰的PMSM控制研究

Research on PMSM Control Based on Variable Universe Fuzzy Active Disturbance Rejection Control

为提高永磁同步电机伺服系统抗负载能力和速度控制的精度,提出一种变论域模糊自抗扰控制策略。变论域模糊控制对自抗扰控制参数进行在线优化调整,提升线性自抗扰控制器自调节能力。在Matlab/Simulink平台进行仿真实验,结果表明,基于变论域模糊自抗扰控制算法,与传统比例微分控制策略相比,具有更好的系统动、静态响应性能,且对负载扰动具有更强的鲁棒性。

A variable universe fuzzy active disturbance rejection control strategy is proposed to improve the anti-load ability and speed control accuracy of permanent magnet synchronous motor servo system.The variable universe fuzzy control optimizes and adjusts the active disturbance rejection control parameters online to improve the self-regulation ability of the linear active distur-bance rejection controller.The simulation experiment is carried out based on the Matlab/Simulink platform.The results show that the variable universe fuzzy active disturbance rejection control algorithm has better dynamic and static response performance of the system than the traditional proportional differential control strategy,and has stronger robustness to load disturbance.
