초록
This paper presents a robust current control in a three phase grid connected inverter using an LCL filter. This controller is based on the optimal control theory and typically designed in a complex-valued state-space. The proposed current controller has a robust tracking performance for the grid voltage harmonics and robustness to parameter error and load variation. Finally, the simulation results are presented to verify the validity of the proposed method.
