摘要

本研究是利用電流與磁流變液支撐墊（electrorheological and magneto- rheological mounts）的液體黏度可調變特性，藉此改變支撐墊之系統阻尼，並利用智慧型控制使整體系統達到最佳減震效果，同時迴避系統共振發生，建立具有適應性與強健性之減震系統。
本文中使用常見的定控制力、天勾控制(skyhook control)、適應滑動控制(adaptive sliding mode control)外，另外應用兩種智慧型控制: 模糊滑動控制(fuzzy sliding mode control)、適應模糊滑動控制(adaptive fuzzy sliding mode control)作為兼具適應性與強健性的控制法。
本文將推導適應滑動控制、模糊滑動控制與適應模糊滑動控制之穩定性，並經由模擬結果，可得知電流與磁流變液支撐墊配合以上控制所得到的減震效果。同時依理論建立實驗後，適應模糊滑動控制的減震效果皆凌駕於其他控制方法，且不需要詳細數學模型，同時針對系統參數的變異及外部振動的干擾，具有適應最佳化減震效果的功能。

In this thesis, intelligent control schemes for electrorheological (ER) and magnetorheological (MR) mounts were proposed. We use electric and magnetic field respectively for the ER and MR mounts to adjust the system damping ratio for vibration attenuation.
We employ the well-known constant control and skyhook control in ER and MR mounts. Further, we proposed adaptive sliding mode control (ASMC), fuzzy sliding mode control (FSMC) to obtain vibration attenuation. We combine ASMC and FSMC to a new controller: adaptive fuzzy sliding mode control (AFSMC). This control can cancel unwanted disturbance in ER or MR mounts without system modeling.
This thesis will show the design procedure of the control schemes and prove the stability of ASMC, FSMC, and AFSMC by the Lyapunov stability theory. The simulation and experimental results demonstrate the effectiveness of these control schemes for vibration attenuation.
