Adaptive Fuzzy Sliding Mode Control for Vibration Isolation in a Magnetorheological Mount
適應模糊滑動模式控制應用於磁流變液支撐墊
摘要
本文提出以適應模糊滑動模式控制應用於磁流變液支撐墊之振動隔離。磁流變液支撐墊藉由適當控制內部之磁場強度可以用來吸收底部之干擾振動，磁流變液支撐墊內部之電流線圈可以產生磁場強度，用來控制此振動抑制系統之阻尼比。然而，磁流變液支撐墊的動態方程式具有高度非線性且難以正確鑑別。我們提出適應模糊滑動模式控制來解決此問題，並以實驗證明其振動隔離能力。此適應模糊滑動模式控制器比知名之天勾控制器更能顯現其振動隔離性能。

In this paper, an adaptive fuzzy sliding mode controller (AFSMC) to suppress the vibration of a magnetorheological (MR) mount is proposed. An MR mount is used for absorbing unwanted disturbances in the base by properly controlling the magnetic fields inside the mount. The current coils inside the MR mount can generate a magnetic field to control the damping ratio of this vibration attenuation system. However, the dynamic equation of an MR mount is highly nonlinear and difficult to identify exactly. To resolve this issue, we propose the use of an AFSMC. The capability of isolating the vibration of an MR mount was proved by experiments in which the developed AFSMC was used. The vibration-isolating performance of the AFSMC was shown to be superior to that of the well-known skyhook controller.
