基于改进型滑模观测器的高速永磁同步电机无传感器控制
Sensorless Control of High-Speed Permanent Magnet Synchronous Motor Based on Im-proved Sliding Mode Observer
摘要
Abstract
In view of the problems such as speed estimation jitter and large phase delay in angle estimation that exist when traditional sliding mode observers are applied in high-speed PMSM(Permanent Magnet Synchronous Motor)drive scenarios,an improved sliding mode observer is proposed.Based on the traditional sliding mode ob-server,the Sigmoid function is used instead of the symbolic function,and phase compensation is introduced to im-prove the stability and control performance of the system.To verify the correctness of the proposed scheme,a corre-sponding experimental platform was built to conduct comparative tests between the traditional and improved sliding mode observers.The experimental results show that,compared with the traditional sliding mode observer,the sen-sorless control system of the improved sliding mode observer has smaller rotational speed errors,more accurate esti-mation of rotational speed and angle,and improves the stability and control performance of the system.It is an effec-tive method to achieve sensorless control of high-speed permanent magnet synchronous motors.关键词
