Abstract

A mechanic position transducer will bring a lot of disadvantages in Interior Permanent Magnet Synchronous Motor(IPMSM) drive system, this paper presents an improved sensorless control method for IPMSM based on high-frequency injection. By using synchronous reference frame filter(SRFF), the positive-and negative-sequence components of current can be extracted from the high-frequency current signal, and then multiply the two components to get the rotor position directly. The simulation and experiment results prove the correctness and effectiveness of the method.
