摘　　要：为了保持质子交换膜燃料电池(PEMFC)的输出电压稳定,该文提出了一种电压动态控制模型。设计了一种自适应模糊比例积分微分(PID)控制器。通过3个模糊控制器实时地整定PID控制器参数。当电池负载发生变化时,通过调节氢气流速控制PEMFC电堆的输出电压。仿真结果表明,所建模型能较好地反映PEMFC的动态性能。与PID控制器相比,自适应模糊PID控制器可以使电池的输出电压快速平滑地过渡到设定值。In order a dynamic control to keep the output model of voltage voltage of proton exchange membrane fuel cell （PEMFC） stable, is proposed. An adaptive fuzzy proportional integral derivative （PID） controller is designed. The parameters of the PID controller are adjusted by three fuzzy controllers instantaneously. The output voltage is controlled by adjusting the flow rate of hydrogen when the load of the fuel cell changes. The simulation results show that the proposed model can effectively describe the dynamic performance of PEMFC. Compared with the PID controller, the adaptive fuzzy PID controller can control the fuel cell＇s output voltage reach the set value more smoothly and quickly.
