量化回授理論是屬於強健控制的一種，它與一般適應控制的最大不同點是當控制區間的參數在預定的範圍中變動時，QFT不須經由參數鑑別的過程來調整控制器的參數。設計者依據給定的響應規格，諸如時域中的上升時間、安定時間、超越量等，設計出適當的補償器，使得系統的輸出響應符合規格之要求。
本文描述了量化回授理論的設計步驟，不但可以設計出適當的補償器，也介紹了迴路整形的技巧，以及前置濾波器的設計，希望對於想研究量化回授理論的設計者，有很大的助益。
此外，本文還對於一個線性單輸入單輸出的飛行器，以MATLAB所提供之高階程式語言，對於此飛行器的參數未確定系統，設計出適當的補償器，最後再驗證系統在預定的範圍中變動時，不同的參數所產生的步階響應以及干擾響應，其效果相當理想。

The quantitative feedback theory is a branch of robust control theories. The main difference between the QFT and the adaptive control is that when parameters of the plant changes in expected region, we do not have to regulate parameters of controller by the process of parameter identification. In order to make the output response fitting with the request of system specifications, designers find appropriate compensator by response specifications such as rising time, settling time, and overshoot.
In this thesis, we not only describe the design steps of the quantitative feedback theory which can be used to design appropriate compensator, but also introduce the technique of loop shaping and the designing of prefilter. We hope that it is helpful to designers who get interested in studying the quantitative feedback theory.
Besides, we also use Matlab to design a proper compensator of parameter uncertainty system about a linear SISO flight vehicle. Finally, from the step tracking response and disturbance response resulted by different parameters with the system change in expected region, we can find that the effect is great.
