Modeling and Control of Small PEMFC Flow System

给出了一种小型质子交换膜燃料电池流量系统的控制模型,根据此模型应用基于CMAC神经元网络的自适应PID控制算法以实现燃料电池阴极和阳极侧压力的协调控制。同时将这种控制算法在一种基于ARM微处理器的硬件平台和可视化的监控组态软件平台(netcon系统)上予于实现。仿真结果和实验结果具有良好的一致性,实际应用效果表明此控制系统运行可靠,使用方便,具有很强的实用价值。

A model was proposed to describe the dynamic behavior of the flow system of a small PEM Fuel Cell. According to this model, an adaptive PID control algorithm based on CMAC neuron network was applied to control the pressure of the cathode and anode. At the same time, a control system based on an ARM microprocessor and visual supervise and control configuration software was designed to realize the control algorithm. The simulation results and practice experimental results have a good consistence. The practical control effect shows that this control system is efficient, economical and reliable and is of very high practical value.
