摘　　要：提出一种基于模糊控制的燃料电池混合动力系统能量管理策略,通过设计模糊控制器的隶属度函数和模糊规则保证燃料电池工作在高效区域和限定的供电能力范围内,并通过积累燃料电池功率增量实现燃料电池功率的逐步变化。基于选定的混合动力系统结构,在MATLAB/Simulink环境下建立了部分子系统的仿真模型。在典型循环工况下,将其与一种有限状态机策略进行对比仿真分析,结果表明该策略能在完成功率分配的同时保证燃料电池处于更健康的工作状态。In this work,an energy management strategy based on fuzzy control for fuel cell(FC)hybrid power system is introduced.The operation of the fuel cell is ensured in the high efficiency area,it is limited within the range of its Maximum power by the proposed controller and the power of FC is changed gradually by accumulating FC power increment.Several subsystem models are established in MATLAB/Simulink according to the proposed structure of hybrid power system.Furthermore,a limited state machine control strategy is used to be compared with the proposed strategy in a typical driving cycle.The simulation results show the proposed energy management strategy can be used to successfully allocate the power and keep FC power system in a better state.
