Two types of pulsating high frequency signal injection control of surface mounted permanent magnet synchronous motor (SPMSM) — pulsating high frequency voltage injection method and pulsating high frequency current injection method are studied at zero and very low speeds in the paper. The basic principle of pulsating voltage injection is analyzed in detail, and the rotor position and speed estimation system is designed to make improvements. On this basis, a novel sensorless control method based… CONTINUE READING
