Investigation of Global Optimization Energy Management Strategy of HEV Based on PMP

Abstract

Abstract:

Dynamic programming usually is used to obtain the global optimal solution of the known driving cycle, but this method needs a large amount of calculation and a long computation time. To solve this problem, the models of the genset and the battery bank were simplified appropriately. Keeping the battery pack energy balanced, the battery state of charge (SOC) was used as the state variable, and the output power of the battery was used as the control variable, PMP was used to obtain the global optimal solution. And the detailed solution process was given. Compared with dynamic programming, the time required to solve by means of the method is very short.

Key words: optimal control, HEV(hybrid electric vehicle), PMP(Pontryagins minimum principle), energy management strategy

摘要：

动态规划常用于求取已知工况的全局最优解，但该方法计算量大、求解时间长。为了解决这个问题，把发电机组和电池组模型适当化简，在保持电池组电量平衡的条件下，以电池组荷电状态为状态变量，以电池组输出功率为控制量，采用庞特里亚金极小值原理算法求解了混合动力汽车的能量管理问题，得到了全局最优解，并给出了详细的求解过程。与动态规划相比，该方法求解需要的时间很短。
