For the fuel cell system, the power converters can be applied widely due to the ability can solve the incompatibility of the bus voltage. To improve the power converter's ability to resist internal and external disturbance and accelerate dynamic response, a novel robust control method is implemented for the two-phase interleaved boost converter (TIBC), which contains the outer voltage regulation loop and the inner current tracking loop in this paper. First, the Model predictive control (MPC) is used to track reference current in the inner loop. The active disturbance rejection control (ADRC) can be applied to regulate the output voltage and generate reference current for the inner loop during the process of outer loop design. Then, the stability of the control strategy is verified by Routh-Hurwitz criteria. Finally, the effectiveness of the proposed control method is verified by simulation results, which indicates that the strong robustness and the fast dynamic response can be realized by the proposed method, when compared with the traditional dual-loop PI controller.
