后驱燃料电池客车的控制策略开发

Development of Control Strategy for Rear Drive Fuel Cell Bus

以某燃料电池汽车为例,介绍了燃料电池汽车动力系统的组成,并根据整车参数和设计目标完成了动力系统的选型参数匹配。为了完成后轴驱动汽车的仿真,对ADVISOR软件进行了后轴驱动模块的二次开发,并利用Matlab/Simulink搭建了能量模糊控制策略,将其封装到ADVISOR中,对其进行验证。将仿真结果与功率跟随式控制策略进行对比分析可知,燃料电池汽车各项动力性指标满足设计需求,且能量利用效率相较于功率跟随式策略有较大的提升。

In this paper,a fuel cell vehicle is taken as an example.The composition of the power system of fuel cell vehicle is introduced,and the parameters matching of the power system is completed according to the vehicle parameters and design objectives.In order to complete the simulation of rear axle drive vehicle,the secondary development of rear axle drive module was carried out for ADVISOR software.The energy fuzzy control strategy is built by MATLAB/Simulink,and is encapsulated in ADVISOR to verify it.The comparison of the simulation results and the power following control strategy shows that the dynamic performance of the fuel cell vehicle meets the design requirements,and the energy utilization efficiency has a greater improvement than the power following strategy.
