Control algorithm of fuel cell/battery hybrid vehicular power system

In this paper, a control strategy for a vehicular power system combined with a proton exchange membrane fuel cell and a battery energy system (BES) has been presented. The control, witch takes into account the slow dynamic of fuel cell and the state of charge (SOC) of BES, is investigated based on the proposed fuzzy logic control (FLC) for the vehicular power system. Fuel cell output power was determined according to the driving load requirement and the SOC, using fuzzy dynamic decision-making and fuzzy self-organizing concepts. Analysis of simulation results is discussed by Matlab/Simulink software to verify the effectiveness of the proposed control strategy. The control scheme can be used to improve the operational efficiency of hybrid power system.
