永磁同步电机自抗扰控制研究

ADRC design for permanent magnet synchronous motor

将自抗扰控制引入永磁同步电机的速度环控制中,为减少算法计算量和降低参数调整难度,对非线性自抗扰控制进行结构优化和线性化处理,完成永磁同步电机的线性自抗扰控制器设计和仿真分析.仿真结果表明,自抗扰控制较常规PI控制抗负载扰动能力强,对不同转速的运行具有较强适应性.

Auto disturbanc rejection controller（ADRC） is proposed for speed control of permanent magnet synchronous motor（PMSM）.In order to reduce computational complexity and parameter setting difficulty,a linear ADRC is designed by means of structure optimization and linearization for nonlinear ADRC,and simulation studies have been carried out for the proposed method.The simulation results show that the speed controller based on ADRC has preferable applicability for different speed control and strong robustness against load disturbance.
