本文利用線性高斯二次和迴路轉移函數回歸(LQG/LTR)控制架構，建立一個燃料處理系統(Fuel processing system, FPS)的最佳控制系統，其中包含前饋控制器及狀態迴授控制器，此系統是針對一個以天然氣和大氣中的氧氣為燃料經由觸媒部分氧化反應器(CPO)，重組後所得到的合成氣體經由純化後，將所產生的氫氣供給質子交換膜燃料電池(PEMFC)堆。此控制系統經由Matlb/Simulink製作成為數學模組，進行動態模擬以及分析系統效能。模擬結果顯示補償系統在時域與頻域都有良好的性能響應。

This paper presents that an optimal control system which consists of both feedforward and state-feedback controllers is designed using a well-developed linear quadratic Gaussian and loop transfer recovery (LQG/LTR) method for a fuel processing system (FPS).This FPS uses natural gas as fuel and reacts with atmospheric air through a catalytic partial oxidation (CPO)，after pure supply to proton exchange membrane fuel cell (PEMFC) stack . The objectives of this paper are to use the Matlab/Simulink software tool to model such an optimal control system and to analyze the system performance. The proposed method achieves better performance and robustness properties in both time-domain and frequency-domain responses.
