基于扰动观测器的永磁直线无刷直流电动机位置控制

Permanent Magnet Linear Brushless DC Motor Position Control System Based on Disturbance Observer

针对永磁直线无刷直流电动机(PMLBDCM)伺服系统抗扰动性能差的特点,研究了使用扰动观测器来抑制扰动,并在电流环设计了扰动观测器,以提高系统的抗扰动性和鲁棒性。仿真结果表明:改进后的系统具有更强的鲁棒性,系统的抗扰动性增强。

In this paper,aimming at the poor performance of the servo system in antidisturbance features for Permanent Magnet Linear Brushless DC Motor（PMLBDCM）,a disturbance observer is designed to increase the system robustness of PMLBDCM drive system.As the demonstration of the results,the system robustness and the ability to reject disturbance of the driver were increased and function of the motor can be more accurate and quicker.
