To reduce the tonal noise of the electric motors, harmonic injection methods can be applied. However, a lot of the existing related work focuses more on improving the optimization process of the parameter settings of the injected current/flux/voltage, which are usually limited to some specific working conditions. ...In this paper, a multi-domain pipeline of harmonic injection controller design for a permanent magnet synchronous motor (PMSM) is proposed. And the structural properties of the machine described by 2-dimensional transfer functions are used to help effectively set proper harmonic injection parameters for different working conditions. ...And the structural properties of the machine described by 2-dimensional transfer functions are used to help effectively set proper harmonic injection parameters for different working conditions. The proposed method is validated by the multi-physics co-simulation of the Prius 2004 PMSM model.
