摘要: 固体氧化物燃料电池(SOFC)工作温度对于其输出电特性的性能起着重要的作用。由于电池在电化学反应过程中,温度特性呈现强非线性等特性,采用常规机理建模后难以在该模型的基础上较好地管理温度特性。为此,设计了面向控制的改进型T-S模型的模糊建模方法来解决此难题。实验仿真结果表明该模糊模型能精确拟合温度动态响应的映射特性,为下一步控制算法的实现奠定了良好的基础。

Abstract: The operating temperature of Solid Oxide Fuel Cell(SOFC) plays an important role on the performance of its electrical characteristics.The SOFC in the process of electrochemical reaction,the temperature characteristics show a seriously non-linear feature.So it is difficult to better control temperature characteristics based on the traditional mechanism model.Consequently,an improved control-oriented fuzzy modeling algorithm is designed to resolve the problem based on T-S model.The simulation results demonstrate that the fuzzy model can accurately fit the mapping relationship of dynamic response for the temperature characteristics,and it lays on the realization of the control algorithm in the next step.
