Abstract :
A repetitive learning control (RC) scheme is proposed for constant-voltage constant-frequency (CVCF) pulsewidth modulated (PWM) DC/AC converter. The repetitive controller is designed to force the periodic tracking error to approach zero asymptotically. The design theory of the repetitive learning controller is described systematically and the stability analysis of the overall system is discussed. The proposed DC/AC converter offers minimized voltage total harmonics distortion under parameter uncertainties and load disturbances. Simulation results are provided to illustrate the validity of the proposed scheme
