Modeling and Energy Management Strategy Research of Fuel Cell Bus

摘要:

基于ADVISOR进行二次开发，建立了燃料电池客车整车前向仿真模型.基于模糊控制方法制定了能量管理策略；为提升燃料电池耐久性，对模糊控制进行改进，提出改进后的模糊控制能量管理策略.中国典型城市工况下的仿真结果表明，改进后的模糊控制能量管理策略在车辆经济性和燃料电池耐久性方面均优于功率跟随式能量管理策略.

Abstract:

A forward simulation model of a fuel cell bus was established based on ADVISOR. A fuzzy energy management strategy was also formulated. In order to improve the fuel cell durability, an improved fuzzy control energy management strategy was proposed. The simulation results under the typical urban operating conditions in China show that the proposed energy management strategy is better than the traditional power-following energy management strategy in terms of vehicle economy and fuel cell durability.
