The Sliding Mode Controller Design of Hydrogen-Powered Electric Bicycle Drive System

This paper presents the design of a sliding mode controller for a half-bridge bidirectional DC-DC converter which is used to control the power from a fuel cell stack feeding to a constant power load in an electric bike application. The aim is the output voltage regulation achieving a good dynamic response. The trial and error technique is used for design process. This controller is then evaluated via simulation results from MATLAB/SIMULINK. The simulation results demonstrate that the proposed sliding mode controller can effectively control the power from the fuel cell to until the constant power load reaches up the rated power. The output voltage regulation can achieve the ISO 21780: 2020 standard. Moreover, the system can provide the fast dynamic responses for the experiment in the future.
