Abstract This paper presents a PIR(proportional integral resonate) current control method for SPMSM(surface permanent magnet synchronous motors) in overmodulation range. The proposed method can effectively reduce THD(total harmonic distortion) of current and the torque ripple in the flux-weakening overmodulation region. In this paper, the mechanism of the disturbance rejection by the conventional method is analyzed, and a novel PIR controlled method is proposed to improve the ability of the system to reject period disturbance signals. Numerical simulations and experiments with a 7-kW prototype are carried out. The results show that the proposed method can effectively reduce harmonic current and torque ripple.
