Abstract:High-order repetitive control can deal with period variation. An augmented second-order repetitive control (RC) scheme is presented to improve system performance under grid frequency variation. Firstly, the relationship between proportional-integral/inertial, multiple-resonant, multi-quasi-resonant control, and second-order RC is analysed. The weight range of second-order RC is discussed. Then, a second-order RC approach augmented by proportional control is proposed for a single-phase grid-tied inverter. Experiments are provided to verify the superiority of second-order RC compared with single-order RC under frequency variation.
