Power distribution control law for FCHEV - a fuzzy logic-based approach

In this paper, the power distribution control method for the fuel cell hybrid electric vehicle (FCHEV) is proposed using the fuzzy logic-based algorithm. The mathematical models of subsystems of a FCHEV are formulated and coded using the Matlab/Simulink software. To show the validity and the performance of the proposed control algorithm, it is applied to a vehicle for a given desired drive cycle. It is shown by simulations that the fuel consumption is reduced compared with the static power control while the battery SOC is maintained at the desired level.
