Abstract :
An improved cascade-type repetitive controller with forward channel gain is proposed for a grid-tied inverter with LCL filter to achieve fast transient response and very low total harmonic distortion. The choices of the RC parameters such as RC control gain krc, the phase compensator parameter m have been discussed. The simulation results show the improved cascade-type RC has fast dynamic response, high steady accuracy and good robustness.
