摘要
介绍了质子交换膜燃料电池(proton exchange membrane fuel cell,PEMFC)空气供应系统的数学模型,包括氧气、氮气流量模型,风机模型和供给返回管道流量模型;给出了一种实用低压风机的特性曲线。基于Matlab进行了数学模型的仿真及分析,并给出了PID控制设计方法及系统模型传递函数的求解过程,最后对控制系统做了仿真与分析。
A mathematic model of air supply system in Proton Exchange Membrane Fuel Cell （PEMFC） is introduced, including the models of oxygen flow, nitrogen flow, blower, supply manifold, return manifold. The characteristic curve of a low - voltage blower is presented. Ttbe simulation and analysis of mathematical model based on matlab is also provided. Meanwhile, the design of PID control and the solution of transfer function of system model are introduced. And finally simulation and analysis of the control system are presented.
