N2 - The dc-dc converter for fuel cell (FC) application inevitably suffers from disturbances, that challenge the bus voltage regulation. In this paper, to better adjust the voltage, an enhanced robust voltage controller based on cascade extended state observer (CESO) is proposed and then applied to the interleaved dc-dc converters for FC application. It treats the converter modeling imperfection and disturbances as the total disturbance, which is then estimated by the CESO and canceled in the control law. Based on the theoretical analysis carried out herein, it is shown that compared with the conventional controller, the proposed one can achieve enhanced robustness and superior voltage quality. Finally, the simulation and experimental results are acquired to demonstrate the effectiveness and robustness of the proposed method.
