本論文為針對被動式氣壓隔振支座合併主動控制進行研究，採用與氣壓彈簧串聯之氣壓式致動器輸出控制力。首先，推導垂直方向與水平方向氣壓隔振支座之線性數學模式，以進行隔振支座之模擬分析。並設計具線上調整功能之控制器於垂直方向主動式氣壓隔振支座，以減少不同頻率下之振動干擾，實驗結果顯示透過自調式模糊控制器能有效抑制振動干擾，並引入前饋振動源，達到即時抑制振動之效果。最後，實驗水平方向主動式氣壓隔振支座之隔振性能。

This thesis is research of active vibration control system incorporated with a passive pneumatic vibration isolator. A pneumatic actuator cascaded with pneumatic spring produces control force. At first, the mathematical model is derived in linear form according to the vibration isolator in the vertical and horizontal direction. Then, simulation and analysis of the vibration isolator can be done. An active vibration isolator using on-line tuning controller is designed to decrease the vibration disturbance in different frequency. The experiment results show that the amplitude of the active pneumatic vibration isolator in different frequency can be reduced effectively through the self-tuning fuzzy controller. Using feedforward control provides that vibration can be reduced instantaneously. Finally, the performance of the active vibration isolator in the horizontal direction is tested.
