Applying advance control strategies, we will control and integrate the Proton Exchange Membrane Fuel Cell (PEMFC) system and Li-Fe battery sets to provide steady power for the proposed electric vehicles. This project will be carried out in three phases: fuel-cell control, motor control, and power management and system integration. First, for the fuel cell control, we can model the PEMFC as a multivariable system whose inputs are hydrogen and oxygen and outputs are cell voltage and current. Because steady power supply is critical for electric vehicles, we will apply robust control algorithms to improve stability and performance of the PEMFC. Second, for the motor control, we will begin with the traditional motor’s control loops and design single-input single-output controllers to improve the system’s stability and performance. Then we will propose multivariable robust control to simplify the control structure of the motors. Lastly, we will combine the PEMFC and Li-Fe battery sets to provide steady power for the electric vehicles. We plan to integrate various electric vehicle systems and verify the results by experiments.燃料電池輕型車輛系統二次電池強韌控制電力管理Fuel-celllight vehicle systemssecondary batteryrobust controlpower management
