Popis:	In this paper, multi-bandwidth repetitive control (RC) is developed and applied to a grid-tied inverter to resist grid frequency variation. In the proposed RC, each of the resonant bandwidth is set individually by the gain of the internal model filter. A design procedure for the internal model filter is proposed, which split the filter into several zero-phase finite impulse response (FIR) filters for reducing the design difficulties. The control structure and stability analysis show that the gain of the multi-bandwidth RC is increased. An example design procedure for the multi-bandwidth RC is presented in details. Comparison experiments with different RCs are performed under deviated grid frequencies, and the results demonstrate the effectiveness of the proposed multi-bandwidth RC scheme.
