摘要

本篇論文的目的是設計一個燃料電池的控制器。這個控制器的法則是以適應控制為基礎，達到使燃料電池可以在負載變動下仍能輸出一所要求的穩定電壓值。
首先，依據燃料電池的電化學反應，得到動態模型，簡化為多輸入、多輸出非線性藕和系統。在不同操作點附近，以線性迴歸模型作系統識別，得到燃料電池的二階模型。基於系統識別的結果，設計單輸入、單輸出的適應控制器，並在實際燃料電池上證實，在固定氫氣流量之下，可用輸入空氣流量穩定控制輸出電壓，即使在負載變動情況下，仍有穩定電壓輸出。

The purpose of this thesis is to design an adaptive controller for Proton Exchange Membrane Fuel Cell. The objective of adaptive control scheme aims to maintain a desired steady voltage output under various loading conditions of fuel cell operation.
First, an application of electro-chemical reactions of fuel cell results in a dynamic model, which is further simplified to a coupled nonlinear multi-input and multi-output system. Second, the linear recursive least square identification scheme is used to generate a 2nd order mathematical model of fuel cell. Based on the identification results, a SISO adaptive controller is designed and tested for the fuel cell. It is verified that the adaptive controller works successfully. At various fixed hydrogen flow rate, the voltage output has been well maintained under various current loads by adjusting the air flow rate.
