利用燃料電池之特性方程式，模擬出不同參數條件下之特性曲線圖，並由燃料電池的特性曲線，可看出為非線性系統，而控制非線性系統的方式有很多種，對於同樣一個系統，若是設計的目標不同，所選用的控制方法也會不同。本文定義目標函數為輸出功率對電流之偏微 ，藉由控制直流對直流升壓式轉換器之開關比，在不需給予任何參考電壓值之情況下，使系統輸出最大功率，經由模擬在不同的操作條件下，系統運作仍保有穩定性與強健性。
　　本文利用極值搜索控制和所使用控制器做比較，在同樣不需要給予任何參考值的情況下，使用相同之系統參數，觀察其追蹤最大功率點之性能，再利用系統參數之變異，比較兩種控制方法的相異之處，並且利用系統參數上的變化，觀察兩種控制法則對系統之強健性。

Due to the nonlinear characteristic of fuel cells, it is very important to implement a maximum power point tracking controller for practical applications. In this dissertation, the controller is applied to manipulate the duty cycle of DC-DC boost converter. Based on the models of fuel cell and converter, the numerical studies of maximum power point tracking controller for fuel cell are illustrated. The results demonstrate the stability of the proposed control system and its robustness to operational environment changes and load variations. Different to the existing approaches, no desired reference voltage value is required in this proposed method.
