两种高频信号注入法与坐标系结合的无位置传感器运行研究
Operation Research on Two Kinds of High-Frequency Signal Injection Method Combined with Coordinate System
摘要
Abstract
Based on the saliency tracking idea,the rotating high-frequency current signal injected into the estimated synchronous rotating coordinate system and the high-frequency pulsating current signal injected into the two-phase stationary coordinate system,which were used in permanent magnet synchronous motor operation control system without position sensor were discussed.The mathematical models of two new high-frequency injection method in rotor position estimation strategy were presented and the spatial position of the rotor demodulation principles using the two new combined high frequency injection method were established.Comparative study of simulation results showed that the pulsating high-frequency current signal injection method combination with the two-phase stationary coordinate system had simpler control structure system and better performance of rotor position estimation.关键词
