Study on Sine Waveform Inverter Based on S-Domain Repetitive Control

The key of the sine waveform inverter design is to assure the quality and stability of its output waveform, as well as the adjusting ability to different kinds of loads. The repetitive control technology is used in this paper to realize the periodic signal tracking control of the sine waveform inverter, and a new method of stability analysis and design of repetitive controlled sine waveform inverter is also proposed. Analog repetitive controller is realized by using analog delay chip MN3304, and repetitive control for the single phase sine waveform controller is researched. The experiment results show that this method is valid.
