Abstract :
One of the major challenges in the voltage regulation of pulse-width modulated (PWM) DC-AC power converters is the time varying nature of the electrical components as well as the loads. In this paper, a time-varying repetitive control approach is developed to track the periodic voltage references for various power electronics applications, where robustness against plant uncertainties is also taken into account by the design of a robust stabilizer. Simulation results are provided to illustrate the control algorithm at load varying conditions.
