Abstract: Based on the machine saliency, the rotor position information could be obtained by injecting fluctuating high-frequency carrier signal into the machine and analyzing the current response, so the sensorless control of permanent magnet synchronous machines could be realized. In this paper, the method of sensorless control of permanent magnet synchronous machines is elaborated based on fluctuating high-frequency carrier signal injection. Then the ways of rotor polarity recognition are compared, the measurement of machine saliency property is introduced, and the means to increase the control accuracy is discussed. Finally, the prospects of development of sensorless control based on fluctuating high-frequency carrier signal injection are presented.
