Research on Z Source Inverter Grid-connected System Based on Repetitive Control and Fuzzy PI Control
摘要
Abstract
Z source inverter has been wildly used because of its powerful boost and buck capability. The traditional control strategy often uses the double loop PI control of outer voltage loop and inner current loop. It was hard to achieve higher control accuracy while using the control of traditional double PI loop and the harmonic distortion rate of grid-connected current was high. The periodic harmonic interference could be better restrained with the repetitive control and the controls parameter could be adjusted online by fuzzy control according to characteristic of nonlinear system. As a result, a new control strategy based on repetitive control and fuzzy PI control was proposed. The harmonic interference could be better restrained by the strategy and the control accuracy was higher. Compared with the traditional method, the effectiveness and validity of the proposed method were verified through the simulation experiment.关键词
