| Abstract |
In this paper, a repetitive controller (RC) is proposed for flyback inverter operating in continuous conduction mode, which has simple structure, low cost, and high efficiency. Conventional controller results in poor control performance due to the effect of the right-half-plane zero in CCM operation. To achieve the fast dynamical response, the repetitive controller is developed and applied to flyback inverter in CCM operation. In RC scheme, a low-pass filter is adopted in the repetitive control scheme to enhance the robustness of repetitive controller. The stability of closed-loop system is derived and the zero tracking error is achieved. Numerical simulations and experiments are performed to validate the proposed control approach. |
