摘　　要：文中提出一种用于混合动力车辆能量管理实时控制的模块化等效消耗最小化策略(ECMS)框架,可实现能量管理实时控制的分布式开发。该框架采用Pontryagin极小值原理求解ECMS最优控制问题。首先,将最优控制问题分解为与各个子系统相关的优化问题;其次,通过Hamiltonian函数将与每个子系统有关的优化问题协调到全局最优;最后,在某款DHT混合动力车辆验证模块化ECMS,此车辆模型支持4种操作模式:2种电动模式、并联模式和串联模式。测试结果表明,模块化ECMS只需修改能量管理系统中功率平衡方程的连接矩阵,即可解决上述每种操作模式的最优控制问题。此框架不需要迭代过程,更适合实时控制的分布式开发。In this paper,a modular equivalent consumption minimization strategy(ECMS)framework for hybrid vehicles is proposed,which can realize distributed development of real⁃time control of energy management system(EMS).The approach is based on applying Pontryagin′s minimum principle to the ECMS optimal control problem.This allows the optimal control problem to be decomposed into smaller optimization problems related to each of the subsystems.Hamiltonian is introduced to coordinate the optimization problems related to each subsystem to the global optimum.The modular ECMS is demonstrated on a DHT hybrid vehicle that can operate in two electric modes,a parallel hybrid mode and a series hybrid mode.The results of real vehicle test show that the modular ECMS can solve the optimal control problem for each of these operating modes by only modifying the connectivity matrices of power balance equation in the EMS.Furthermore,this approach does not require the initial iteration of the equivalence factor,which is more suitable for distributed development of real⁃time control.
