| 摘 要： | 针对混合动力汽车设计参数众多的状况,提出了一种对混合动力汽车传动系统参数和控制参数同时进行优化的多目标优化新方法--自适应遗传算法.在ADVISOR平台上,以一辆使用逻辑门限控制策略的并联混合动力汽车为例,分析并建立了以动力性能指标为约束的混合动力汽车参数优化的非线性规划模型,其目标函数包含最小油耗和最佳排放性能.针对遗传算法容易早熟等不足,采用带自适应交叉和变异算子的遗传算法和模拟退火技术相结合进行求解.仿真结果表明了所提出方法的有效性.

| Abstract: | In view of the large amount of parameters of hybrid electric vehicle(HEV),a new multi-objective optimization scheme for HEV based on adaptive genetic algorithm is proposed,in which the optimizations on both the power-train parameters of HEV and control parameters are concurrently performed.Taking a parallel HEV using logic threshold control strategy as an example,a nonlinear programming model for optimization on HEV parameters is set up on ADVISOR platform,with the objective functions of minimizing both fue... |
