Abstract :
A new deadbeat control with disturbance compensation method for FPGA based hardware controller for utility interactive inverter system is proposed to enhance the robustness for utility grid variations with small LC filter components. Variation of line impedance of the utility grid is defined as a disturbance, the disturbance compensator compensate it with the real time digital feedback control. Through simulations and experiments, the superiority of the proposed method is verified compared with conventional digital control methods.
