摘　　要：介绍了一种用于并联混合动力电动汽车(Parallel Hybrid Electric Vehicle,PHEV)能量管理策略开发的鲁棒Hinf算法,该方法用于确定发动机和电池之间的功率分配比,并将电池的能量状态保持在合理的范围内,防止电池出现故障。首先阐述了由发动机部分、电动机部分和电池部分组成的系统模型(采用等效电路模型);然后阐述了考虑电池故障和控制信号限制的控制系统结构;最后推导出了控制器,并对特定PHEV进行了仿真。This paper presents a robust Hinf approach for the energy management strategy development of a parallel hybrid electric vehicle(PHEV),which is applied to determine the power split ratio between engine and battery,also the state of energy of the battery is maintained within a reasonable range to prevent the battery from undesirable fault.The system model which consists of the engine part,the electric motor part and the battery part(a equivalent circuit model)is given first.Then the control system structure is given,taking into account the battery fault and the control signal limit.Finally,the controller is derived and some simulations for a specific PHEV are included.
