Dynamic Modeling and Analysis of Fuel Cell Powered Electric Vehicle

Abstract

An Electric Vehicle is digitally simulated and presented in this paper. The proposed electric vehicle scheme has four key subsystems to ensure stabilized driving speed. The first subsystem includes Fuel Cell as clean energy resource. The second is the deriving electric motor of the vehicle. The third is the interfacing converters between the energy resource and the driving motor. The fourth subsystem is the control strategy to adjust the hydrogen rate to the fuel cell and to regulate the motor speed to follow up the vehicle load. The different vehicle configurations using either DC or AC motor, PID, Sliding Mode (SM) and direct torque Controllers (DTC) are digitally simulated and compared using Matlab/Simulink/Sim-Power software environment to validate the vehicle performance under varying speed and to justify the appropriate vehicle configuration.
