质子交换膜燃料电池电堆温度特性的模糊建模

Fuzzy Modeling for PEMFC Stack Temperature Characteristic

根据PEMPC电堆温度控制的需要,建立了PEMFC电堆的工作温度与运行参量之间的定量关系模型,为建立面向控制的PEMFC温度非线性模型提供了一种新思路.在建模过程中,采用模糊辨识方法建立PEMFC控制系统的模糊模型,仿真和实验结果表明,该模糊辨识方法对质子交换膜燃料电池电堆的建模和控制提供了一条可供参考的途径.

According to demands of the control design,a quantitative relations model control-oriented idea of proton exchange membrane fuel cell (PEMFC) is developed between the temperature of the stack and operation variants. In the process of model, the fuzzy model of PEMFC is built on-line using fuzzy identification. The modelling method is simple and accurate. The results of simulation demonstrate this approach is applicable and referencable for the modelling and control of PEMFC stack.
