摘要
在对质子交换膜燃料(PEMFC)的工作原理进行研究分析的基础上,对其进行数学描述,建立质子交换膜燃料电池的数学模型.根据缩减域控制原则进行模型预测控制器的设计,对比分析分别采用氧气压力和氢气压力作为控制变量时输出电压的变化.仿真结果表明当选择氧气压力作为控制变量时能够获得比较理想的控制效果.
In this paper, based on the research and analysis of the proton exchange membrane fuel cell （PEMFC） working principle, the PEMFC＇s mathematical description is given and the mathematical model is established. On the basis of the receding horizon control, the model predictive controller is designed. The output voltage is analyzed and compared when hydrogen pressure and oxygen pressure are chosen as the control variable, respectively. The result shows that when oxygen pressure is chosen as the control varia- ble, the use of this MPC controller can get an ideal control effect.
