Harmonic current suppression method for marine permanent magnet synchronous motor based on SOGI
In this paper,a harmonic current suppression method based on SOGI is proposed for the harmonic current problem in marine permanent magnet synchronous motors.In this method,the harmonic component in the current is obtained by SOGI conversion of the grid current,and the PI controller is used to compensate for the harmonic current.Finally,the effectiveness and superiority of the proposed method are verified by simulation and experiment.
