摘要
针对燃料电池汽车能量管理的经济性优化问题，提出了一种基于动态逻辑规则的多能源动力系统能量优化管理策略。该策略在保证功率平衡控制的基础上，根据负载及系统状态的变化动态调整能量流在不同动力源的分配，使燃料电池尽可能工作在高效率区，从而提高整车经济性。通过离线仿真对所提出的动态逻辑规则参数进行了优化设计。仿真及转鼓试验的结果证明，所提出的能量优化管理策略有效，能够在保证动力性及功率平衡控制的基础上，显著提高经济性，具有一定的实用价值。
Considering that for fuel cell hybrid vehicles, optimization of power management is very important for vehicle econo： my, this paper proposes a power optimization control strategy based on the dynamic logic rule to improve the efficiency characteristic of the fuel cell engine. Based on the control of power equilibrium, the strategy dynamically adjusts the distribution of the energy flow between the fuel cell engine and power batteries according to the changes of the power train state and the vehicle load, to make the cell work in the high-efficiency area as possible as it can, so the whole vehicle economy is improved, The control parameters based on the dynamic logic rule were optimized by simulation. The results of the simulation and the field show that the proposed power optimization management strategy is effective in improvement of the vehicle economy.
