Abstract

As for such issue as weak dynamic response and weak interference ability suppression in the conventional grid connected inverter

in this paper

a kind of control strategy combining repetitive control with proportional resonance control is proposed. The proportional resonance control is used to eliminate steady error and improve dynamic response. The repetitive control is used to track periodic reference value

compensate distortion due to harmonics and

at the same time

for attaining low THD and quick steady state process

the feed forward control is introduced into the design of controller

the stability of the designed controller is verified in accordance with the bode plot. The simulation model and experimental sample of 3 kW grid connected inverter are set up so to verify the correctness of theory analysis and give the experimental waveform.
