基于高频信号注入SPMSM无位置传感器控制系统
Research on SPMSM Sensorless Control System Based on High Frequency Signal Injection
摘要
Abstract
A control system with improved modulation method and position compensation method is studied to solve the problems of unstable factors and the location estimation error in high frequency signal injection sensorless control system for SPMSM.Based on the analysis of the high frequency signal injection method,the influence of the phase shift of the filter on the stability of the system and the inaccurate position estimation error caused by the high frequency model of the motor are analyzed.The control system is designed and simulated in Matlab/Simulink and the simulation platform of dSPACE system.The simulation and experimental results show that the control system with improved modulation method and position compensation method has good stability and position error compensation effect.关键词
