摘　　要：针对某双行星排式混合动力汽车进行构型分析,提出该混合动力系统基于动态规划法的能量管理控制策略。通过优化选取系统状态变量和控制变量,确定状态转移规则以及油电转化系数,建立以等效燃油消耗最小为目标的代价函数来评价能量管理控制策略。在Matlab/Simulink仿真平台下进行NEDC工况仿真,结果表明,与逻辑算法相比,基于动态规划法设计的能量管理控制策略可显著提高仿真性能,改善混合动力汽车的燃油经济性。On the basis of the configuration analysis of a certain HEV(hybrid electric vehicle)with double planetary gears,a hybrid power system energy management control strategy based on dynamic programming method is proposed.By optimizing the selection of system state variables and control variables,the state transition rules and oil-electricity conversion coefficients are determined,based on which,the cost function that takes the minimum equivalent fuel consumption as the target is established to evaluate the energy management control strategy.The NEDC(new European driving cycle)working condition simulation by Matlab/Simulink simulation platform shows that,in comparison with the logic algorithm,the energy management control strategy based on dynamic programming method can significantly improve the simulation performance and improve the fuel economy of HEVs.
