摘　　要：如何改善燃料电池的输出性能是燃料电池电动车的一个重要问题.首先燃料电池是一个多变量复杂系统.燃料电池的工作和环境温度、流量及湿度对燃料电池实际功率输出有重大影响.然后提出一种自适应模糊复合控制算法。考虑到燃料电池的多动态特性,加入自整因子层对量化因子和比例因子进行在线修改,从而改善了控制器的静态和动态特性.有实验结果证明所提出算法的有效性.最后,详细设计燃料电池电动车的能量控制系统.How to improve the output performance of the fuel cells is important for the fuel cell-electric vehicles. The fuel cells are a multi-input variables system, whose maximum power output is strongly affected by the surrounding temperature, air flow and humidity. In the adaptive fuzzy control algorithm presented here, the multi-dynamic characteristics of the fuel cells is considered, and a self-adjusting layer is made to modify the quantitative factors and proportional factors for improving its static and dynamic characters. The effectiveness of the proposed algorithm is validated by the experimental results. Finally, the implementation of the energy control system on fuel-cell electric vehicles is introduced in detail.
