摘　　要：针对燃料电池混合电动汽车复杂的拓扑结构,提出一种改进软执行者-评论者(SAC)算法的能量管理策略。首先,利用自适应模糊滤波对需求功率进行频率解耦来实现功率分层,让超级电容来提供/吸收需求功率中的峰值功率。然后,通过采用基于等效消耗最小的思想构建SAC的奖励函数,以实现降低氢耗量和改善燃料电池工作效率的目标,并优化燃料电池和锂电池的功率分配。在训练过程中,引入启发式经验回放机制来提高SAC算法的收敛性能和优化效果。最后,在多种典型工况下仿真并进行平台试验。结果表明:所提策略在燃料经济性上与传统SAC策略相比平均提高6.4%,并且在面对极端工况时,依旧能够保证燃料电池的平稳运行,实现对3能量源燃料电池汽车的能量管理。For the complex topology of fuel cell hybrid electric vehicle(FCHEV),an energy management strategy based on improved soft actor-critic(SAC)was proposed.Firstly,an adaptive fuzzy filter was utilized to complete frequency-based decoupling of power demand for achieving power stratification,and the ultracapacitor was employed to provide/absorb the peak power in the power demand.Then,the idea of the equivalent consumption minimization strategy was introduced to construct the reward function of SAC,which aims at accomplishing the goal of reducing hydrogen consumption and improving fuel cell efficiency,and optimizing the power distribution between fuel cell and lithium battery.In the process of training,the heuristic experience replay mechanism was introduced to enhance the convergence performance and optimization effect of SAC algorithm.Finally,the simulation and platform test were carried out under various typical driving cycles.The result shows that compared with the traditional SAC strategy,the fuel economy of the proposed strategy is improved by 6.4%.Furthermore,in the face of the extreme driving cycle,the proposed strategy can still guarantee the smooth operation of fuel cell and realize the energy management of FCHEV with three energy sources.
