摘要
近年来,凸极式永磁同步电机(IPMSM)的无传感器控制已成为一个热门的研究领域。大量的无传感器控制方法被提出,但绝大多数方法在低速情况下效果不好。此处介绍了有效磁链的概念,并基于此设计了转子位置和速度观测器。该观测器无需速度自适应,因此在低速时的转速估计误差不会影响观测器的表现。通过实验结果证明该无速度传感器控制方法的有效性及实用性。
In recent years, sensorless control of interior permanent magnet synchronous motor（IPMSM） has been a research area of significant interest.A multitude of solutions have been proposed for sensorless operation but most of them fail to deliver satisfactory performance in the low speed region.This study describes the active flux concept which is used to design a rotor position and speed observer.The observer does not require any speed adaptation, so the speed estimation errors especially in the low speed region do not affect the performance of the observer.The experimental results verify the effectiveness and applicability of the sensorless approach.
