Simulation of sliding mode controller of boost converter for fuel cell hybrid electric vehicle

This paper deals with simulation of fuel cell hybrid electric vehicle (FCHEV) configuration with special attention to sliding mode controller (SMC) for boost converter (BC). MATLAB/Simulink software tool is used for the simulations. Proportional-integral (PI) and SMC for fuel cell (FC) side BC is modeled and simulated. The SMC shows slightly lesser oscillations before steady state as compared with PI controller. Also, the SMC shows faster response time of about 0.5 seconds as compared with 3 seconds using PI controller. Integration of FC connected to BC along with SMC, DC motor with controllers and battery pack with bidirectional converter are made to verify the motor response in FCHEV configuration.
