摘　　要：针对双模式机电复合传动系统,运用最小值原理对系统的功率分配进行优化控制策略的研究。在保证系统电池荷电状态平衡的前提下,以燃油消耗最少为优化目标,并基于所设计的优化求解流程和建立的系统数学模型,确定最优的系统工作状态。仿真结果表明,基于最小值原理的优化控制策略能够改善机电复合传动系统的燃油经济性。研究结果可为系统实时优化控制策略的制定提供依据。Based on Pontryagin＇s minimum principle,an optimal control theory was applied to derive a methodology for the power split algorithm of two-mode EMT system.Under the premise of sustaining the battery state of charge（SOC）,the fuel consumption was used as the optimization objective function.Then,the optimal system working conditions were determined according to the optimization process and the mathematical model of the system.The simulation results show that the research of EMT control strategy has significant oil-saving effect.The control strategy is effective and provides the foundation for developing and optimizing the real-time control strategy.
