摘　　要：为了提高燃料电池(FC)混合动力汽车(HEV)的经济性,提出一种利用模糊逻辑控制(FLC)的方法对其实现能量管理策略(EMS)。以氢耗量最优为目标,加入超级电容器作为辅助能源,考虑汽车驱动与制动2种状态,把需求功率、超级电容荷电状态、燃料电池的工作效率,添加为模糊控制器输入变量,对模糊规则进行改进。引入改进的麻雀搜索算法(ISSA)对模糊控制器的隶属度函数进行优化,采用Circle映射初始化麻雀种群,同时引入随机游走策略对全局最优解扰动。采用Advisor软件和Matlab/Simulink环境建模并进行联合仿真。结果表明:本文能量管理策略,在城市道路循环工况(UDDS)和高速公路燃油经济性测试工况(HWFET)下,等效氢耗量分别减低了29.38%和29.88%,同时,也减少了燃料电池在运行时的变载次数,使得燃料电池寿命得到延长。A Fuzzy Logic Control(FLC)method was proposed for Energy Management Strategies(EMS)to enhance the fuel efficiency of the Fuel Cell(FC)Hybrid Electric Vehicle(HEV).With a supercapacitor as an auxiliary energy source to optimize the hydrogen consumption,the power required under working conditions,the State of Charge(SOC)of the supercapacitors,and the fuel cell’s working efficiency were incorporated as input variables into the fuzzy controller to improve the fuzzy rules,considering the two states of automobile drive and braking.The Sparrow Search Algorithm(SSA)was employed to optimize the membership functions of the fuzzy controller.The circle mapping technique was utilized for initializing the sparrow population,with a random walk strategy to perturb the global optimal solution.Advisor software and the Matlab/Simulink environment were employed for modeling and conducting joint simulations.The results show that the energy management strategy reduces 29.38%and 29.88%of equivalent hydrogen consumption,specifically under the Urban Dynamometer Driving Schedule(UDDS)and the HighWay Fuel Economy Test(HWFET)operational scenarios,with decreasing the occurrence of load changes during the fuel cell’s operation,and consequently enhancing its longevity.
