Abstract:	本論文的主要研究是利用輸入－輸出迴授線性法則之理論設計軸流式壓縮機控制器，特別是針對軸流式壓縮機激振(surge)現象之改善設計。在系統之機構方面，本研究採用二種控制方式：一是透過節流閥的開關；另一則是透過耦合閥門控制(close-coupled valvecontrol)以改善系統激振之動態行為。此二種的控制器設計是以軸流式壓縮機二個輸入之中的一個做為系統迴授線性化的控制輸入。本論文提出之系統整體控制律可以避免激振現象的發生。另外，數值分析結果也驗證本論文提出的迴授線性化控制律之成效。 In this paper, input-output feedback linearization scheme is employed to stabilize the instabilities of axial flow compressor, specifically, for the so-called "surge" behavior. Two types of actuators are considered for the study. One is the throttle opening, and the other is the close-coupled valve. The axial flow compressors are found to be feedback linearizable via either of the two control inputs. Overall control law is then proposed to prevent the occurrence of the surge oscillation. Numerical results are also given to demonstrate the effectiveness of the proposed designs.
