摘要
针对车用燃料电池蓄电池混合动力系统的特点设计了优化的能量管理策略。采用动态规划算法对目标驾驶循环进行全局优化,对最优能量分配策略进行分析,提取相应的控制规则,并设计了基于模糊控制的燃料电池混合动力系统实时控制策略。仿真及台架试验结果表明该控制策略能够控制燃料电池工作在高效区,提高整车的燃料经济性。
An optimal energy management strategy was designed based on the characteristics of typical fuel cell battery hybrid powertrains. An optimal global energy distribution strategy was obtained using a dynamic programming （DP） algorithm for representative driving cycles. These results were used to develop a fuzzy logic-based real time control strategy for fuel cell hybrid powertrains. Simulations results and test-bed experiments show that the strategy controls the fuel cells always work in the high efficiency region to improve vehicle fuel economy.
