Study and design of a power management system using two-stage controller for PEM fuel cell vehicles

Abstract

This work is within the scope of the study and modeling of fuel cell based systems for energy optimization. In fact, the electric vehicle is based on the proton exchange membrane fuel cell. The energy optimization problem is explored and inspected using a two-stage controller. In first stage, a predictive controller is designed based on the equivalent consumption minimization strategy. The second stage is an efficient tracking system. The system is tested with a standard driving cycle UDDS. It is simulated in Matlab/Simulink environment. The achieved results show that the two-stage controller utilization ensures the energy consumption minimization. Furthermore, it protects the fuel cell and the battery life.
