Research on Photovoltaic Grid-Connected Inverter Based on Repetitive and PI Control
摘要
Abstract
Grid-connected inverter control strategy is the most important link in the photovoltaic inverter control module,and how to make the output current of the inverter to track the grid voltage to achieve the same frequency and the same phase and improve the quality of the output waveform is the key of the inverter control. To solve the problem,deep analysis of Repetitive control principle is made,and three control methods which are PIclosed-loop control,repetitive control and repeat and PIcomposite control are designed to adjust the periodic disturbance. And simulation in MATLAB/Simulink environment is made. It achieves good grid inverter control effect. The simulation fully results that repeat and PIcomposite control has better inhibition to the periodic disturbance.关键词
