Abstract: In order to improve the output voltage distortion of the inverter under rectifier loads, a control method which combines the repetitive control theory and the predictive control theory was proposed. Then the analysis of stability for repetitive control and the predictive control was presented，and the design method of the control parameters for repetitive control and predictive control was also given. The feature of repetitive control and predictive control was analyzed based on the experiment. The experimental results show that repetitive control can reduce the voltage distortion under rectifier loads effectively, and the dynamic performance of the system can be enhanced by means of current predictive control.
Key words: repetitive control; predictive control; inverter; rectifier load
