摘要为了研究燃料电池系统的特性以及空气系统对燃料电池特性的影响，利用Simulink仿真软件对燃料电池系统进行建模，模型包括电压模型、空压机模型、阴极模型、阳极模型.分别通过前馈比例-积分-微分（proportional-integral-differential，PID）和模糊PID对燃料电池空气系统进行控制.结果表明：在负载电流变化时，前馈PID和模糊PID都能够使过氧比达到设定的常数值2.0附近，但模糊PID比前馈PID响应更快，且模糊PID控制下的燃料电池输出功率波动较小，燃料电池系统更加稳定.

Abstract：To investigate the characteristics of fuel cell systems and the influence of air systems on fuel cell characteristics, Simulink simulation software was used to model the fuel cell system with voltage model, air compressor model, cathode model and anode model. The fuel cell air system was controlled respectively through proportional-integral-differential (PID) and fuzzy PID. The results show that when the load current changes, both the feedforward PID and fuzzy PID can make the oxygen excess ratio reach the set constant value of 2.0. However, the fuzzy PID responds faster than the feedforward PID, and the output power of the fuel cell under fuzzy PID control fluctuates less, which makes the fuel cell system more stable.

Key words： fuel cell Simulink modeling excess oxygen ratio feedforward PID fuzzy PID
