传统PI控制无法实现永磁同步电机(PMSM)交直轴间的完全解耦.为此该文提出一种基于跟踪微分观测器(TD-NLESO)的永磁同步电机(PMSM)控制系统.采用线性自抗扰控制器(LADRC)对扰动的观测来抵消电感耦合项,实现电流环解耦,并对线性扩张状态观测器的结构进行改进,提高对扰动的观测速度;同时设计含预估因子的跟踪微分器以克服控制延时问题;最后,通过实验验证该策略具有可行性和良好的控制性能.
Permanent Magnet Synchronous Motor Control System Based on Tracking Dif-ferential Observer
In traditional PI control systems,complete decoupling between the AC and DC axes cannot be achieved.This article proposes a permanent magnet synchronous motor(PMSM)control system based on tracking differential observer(TD-NLESO).Using a linear active disturbance rejection controller(LADRC)to counteract the inductive cou-pling term and achieve current loop decoupling,the structure of the linear extended state observer is improved to im-prove the observation speed of disturbances.Simultaneously design a tracking differentiator with an estimation factor to overcome control delay issues.Finally,the feasibility and good control performance of this strategy were verified through experiments.
