Abstract：High frequency (HF) signal injection is a classical method widely used in sensorless control of interior permanent magnet synchronous motors (IPMSM), acquiring good dynamic and steady characteristics. However, the audible noise created by the injected HF signal becomes one of the main sources of noise. In this paper, a variable frequency current injection method is proposed to reduce this noise. By continuously changing the frequency of harmonic current, the energy of the harmonics in the spectrum is dispersed, and the peak is eliminated. In this way, the high frequency current noise can be reduced. In order to realize the variable frequency harmonic current injection, the current loop of the motor is redesigned, and the high frequency current signal injection is realized by the linear active disturbance rejection controller and the resonance controller. The experimental results show that this method can effectively improve the spectral distribution of harmonic current and reduce the high frequency current noise.
