摘要
对传统脉振高频注入法进行了分析,并在传统脉振高频注入法基础上,加入虚拟高频旋转坐标,对传统脉振高频注入法进行改进,提出基于虚拟脉振高频注入法的永磁同步电机位置检测方法。该方法和传统脉振高频注入法相比,不需要PI调节,工程实现简单,并且解决了传统脉振高频注入法的过零点问题。通过仿真和工程实验,验证了该方法的正确性和有效性。
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.
