Abstract The repetitive control is widely used in inverters, the traditional parallel-type repetitive control(PRC) scheme improves dynamic response with PI control in parallel. The improved parallel- type repetitive control(IPRC) scheme can optimize both tracking performance and anti-jamming performance of the system at the same time, compared with PRC. This paper proposes a weighted parallel-type repetitive control(WPRC) scheme, which achieves excellent dynamic response during load variation. Meanwhile, system with WPRC scheme still achieves the index of total harmonic distortion(THD). Repetitive control design based on specific frequency notch filter is first given. Then the theoretical analysis and design of comparing IPRC and WPRC in respect of dynamic response is presented. Finally a 120W vehicle inverter prototype has been constructed to the proposed control scheme. Experimental results show that the WPRC controlled inverter can achieve both good dynamic response and low THD.

Key words： Parallel-type repetitive control notch filter vehicle inverter dynamic response
