| 摘 要： | 本文提出一种兼顾电池SOC限值方法的混合动力汽车多种群遗传模糊控制策略。引入模糊逻辑控制以增强整车控制系统鲁棒性、实时性;用多种群遗传算法对模糊变量隶属度函数进行优化,使在模糊逻辑控制下整车燃油消耗得到降低;使用电池SOC限值方法避免电池在SOC过低时继续放电。利用matlab平台联合advisor软件进行联合仿真实验,仿真结果表明多种群遗传模糊模糊控制策略能够比advisor软件默认的电机辅住控制策略燃油经济性提高6.96%的情况,SOC限值方法使电池工作在更加合理的SOC值区间范围内,有效保护电池。

| Abstract: | In this paper,a multi population genetic fuzzy fuzzy control strategy for hybrid electric vehicle is proposed,which takes into account the battery SOC limit method.Fuzzy logic control is introduced to enhance the robustness and realtime performance of the vehicle control system;multi-population genetic algorithm is used to optimize the membership function of fuzzy variables to reduce the fuel consumption of the vehicle under the fuzzy logic control;the battery SOC limit method is used to avoid the battery working at the SOC too low.The simulation results show that the multi-population genetic fuzzy control strategy can improve the fuel economy by 6.96%compared with the default motor auxiliary control strategy of advisor software.The SOC limit method makes the battery work in a reasonable range of SOC value and effectively protect the battery. |
