流場在離心式壓縮機內的不穩定現象，如喘振是在發動機運轉下所造成主要的不穩定，由於這種不穩定會因造成渦輪發動機能量損失而導致運作效能降低，嚴重的話會因震動而造成結構上的破壞。此研究的目的是在離心式發動機中，利用軸承扭力的輸入來做控制，藉此用函數近似法控制器來控制上述的不穩定現象，並藉由壓縮機的數學模型來模擬真實的壓縮機系統。 Compressor instabilities in fluid field such as surge is the main instabilities phenomena in operation of jet engine. It reduces the performance by energy loss and causes structural damage by vibration due to the instabilities. In this study, we use drive torque actuation in active surge control of centrifugal compressor by function approximation approach to design. The proposed method is simulated on a compressor model using a real compression system.
