Abstract

A linear phase lead repetitive controller is introduced for the constant-voltage constant-frequency (CVCF) pulse-width modulated (PWM) DC-AC converters. The design of the repetitive control (RC) is discussed. Since phase lead can compensate the phase lag of feedback control system, more harmonics can he suppressed which leads to a low total harmonic distortion (THD) of the output voltage in the presence of nonlinear load disturbances and parameter uncertainties. Simulation results show that this method has a fast response and good tracking accuracy.
