摘要
Abstract
Nowadays,the sensorless position detection method of permanent magnet synchronous are mainly divided into two types:one is based on the fundamental wave detection;the other is based on the saliency effects.This paper is mainly based on the saliency effects.It analyses the traditional high-frequency pulsating injection method and improves traditional method by adding a virtual high-frequency rotating coordinate.A position detection method of permanent magnet synchronous motor based on virtual pulse high frequency injection is proposed.Compared with traditional pulsating high-frequency injection method,this method does not require PI regulator,which can be achieved by project easily.At the same time,this method solves part of zero-corssing problems of traditional pulsating injection method.The method is verified by simulation and experimental test.关键词
