Sensorless control of PMSM based on fluctuating high frequency voltage signal injection WangFei, Fan Qi-Fu (Institute of Automation, Shanghai Jiao Tong University, Shanghai 200240) Abstract: A method to implement sensorless control of Surface Mounted PMSM based on fluctuating high frequency voltage signal injection was introduced. With the magnetic saturation of Surface Mounted PMSM, rotor position could be obtained when a fluctuating high frequency voltage signal was injected at synchronous coordinate and a coordinate transformation and demodulation were made against the stator current. The simulation results verified the method.
