中文摘要 | 本文提出以磁流變液支撐墊配合模糊滑動控制器,用以抑制底部基板震動的減震系統。近年來,磁流變液是半主動控制領域中熱門的智慧型材料。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鑑別,在此提出利用簡易的模糊滑動控制,抑制非線性系統的未知震動干擾。此控制器可有效解決傳統滑動控制造成切跳的問題,同時可利用Lyapunov穩定理論推得模糊控制規則。本文內容有一維與二維模糊滑動控制的模擬結果,兩者皆可有效減低震動,並提供常用的天鉤控制以及具有適應性滑動控制結果作為比較。 |
英文摘要 | In this paper, a magnetorheological (MR) mount with fuzzy sliding mode controller (FSMC) is studied for vibration suppression when the system is subject to base excitations. In recent years, magnetorheological fluids are becoming a popular material in the field of the semi-active control. However, the dynamic equation of an MR mount is highly nonlinear and it is difficult to identify. FSMC provides a simple method to achieve vibration attenuation of the nonlinear system with uncertain disturbances. This method is capable of handling the chattering problem of sliding mode control effectively and the fuzzy control rules are obtained by using the Lyapunov stability theory. The numerical simulations using one-dimension and two-dimension FSMC show effectiveness of the proposed controller for vibration suppression. Further, the well-known skyhook control scheme and an adaptive sliding mode controller are also included in the simulation for comparison with the proposed FSMC.. |
