Simulation and Experiment of Power Response Control Strategy for Vehicle Fuel Cell

Abstract

With the development of the new energy automobile industry, fuel cell vehicles have a broad development prospect. Due to the rapid acceleration and deceleration in vehicle operating conditions, the dynamic response of fuel cell is highly required. Firstly, this paper introduces the working principle and system structure of the fuel cell system. Secondly, the AMESim simulation model of the fuel cell system and air loop is established. Base on Simulink, the air flow-pressure decoupling and PI fusion control strategy is developed. Finally, the model co-simulation is carried out, and the strategy is applied in the fuel cell system test bench. The results show that the decoupling and response can be realized through the simulation, and the power response rate can reach 8kW/s through the bench test, which can basically meet the power response demand of the vehicle fuel cell.
