Abstract This paper presents a nk±m order harmonic repetitive controller for high-performance constant voltage constant frequency (CVCF) PWM converter systems. The proposed controller, which provides a universal formula for different repetitive controllers, can achieve zero-error tracking or perfect disturbance rejection for particular nk±m order harmonic components. It occupies less data memory than a conventional repetitive controller does. Moreover, it offers faster convergence rate, low tracking error and very low total harmonic distortion (THD). An application example of three-phase PWM inverter is provided to demonstrate the effectiveness of the proposed nk±m order harmonic repetitive control scheme.

Key words： Internal model principle(IMP) repetitive control(RC) nk± m order harmonics PWM converter
