Abstract

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.
