摘　　要：为了提高车用燃料电池的耐久性,提出基于模糊控制和自适应FIR滤波控制的复合能量管理策略。通过设计以蓄电池SOC和整车需求功率与燃料电池高效区下限之差为模糊输入量,以燃料电池系统输出功率比例系数为输出量的模糊控制器,再通过自适应FIR滤波控制可以有效避免燃料电池因启停、持续低速和怠速工况以及动态循环工况导致的耐久性差的问题。将该复合能量管理策略与模糊控制能量管理策略进行仿真对比,结果表明,该复合能量管理策略保证了燃料电池的经济性,而且减少了引起燃料电池寿命衰减的工况,改善了其耐久性,同时保证了蓄电池的安全性。In order to improve the durability of vehicle fuel cells,a composite energy management strategy based on fuzzy control and adaptive FIR filter control was proposed.By the design of a fuzzy controller using the battery SOC,and the difference between the vehicle′s required power and the lower limit of the fuel cell high efficiency zone as as the fuzzy input,and the fuel cell system output power proportional coefficient as the output,and by adaptive FIR filtering control,the fuel cell can effectively avoid the problems of poor durability caused by starting and stopping,continuous low speed and idling conditions and dynamic cycling conditions.The strategy of composite energy management and the strategy of fuzzy control were simulated,and the two strategies were also compared with each other in this research.The consequences imply that the strategy of composite energy management not only guarantees the economy of the fuel cell,but also reduces the working conditions that causes the degradation of the fuel cell life.This strategy of composite energy management improves the durability of the fuel cell and at the same time ensures the safety of the battery.
