摘要

磁流變液(magnetorheological fluid，簡稱MRF)為一種性能突出的智慧型材料，在外加磁場作用下，可改變其物理特性(黏滯性)，其過程迅速、可逆、可控性高，根據上述特性，在車輛領域則可設計成煞車器、懸吊系統、離合器等。
本文可分為三大部份: 第一部份為推導機車單輪煞車動態方程式，並討論車輛防鎖死煞車系統(Anti-lock Braking System，ABS)作動原理。第二部份針對磁流變液作探討，並設計一實驗平台測試磁流變液煞車器之暫、穩態扭力輸出性能，以建構數學模型。最後則是結合一、二部份，依據模糊理論以滑差及滑差變化率為參考輸入設計一控制器，利用響應速度快的特點，使磁流變液煞車器實現車輛防鎖死煞車系統，並以電腦模擬討論其系統特性，最後以實驗法驗證系統可行性。

Magnetorheological fluid(MRF) is a kind of smart material that has great performance. Its physical property (viscosity) can be changed by applied external magnetic field. The changing process is fast, reversible and highly controllable. In automobile field, this property is usually applied to design new brake, suspension, clutch, etc.
There are three parts in this thesis. The first part derived the dynamic braking models of single wheel for a motorcycle, and discussed the nature of Anti-lock Braking System(ABS). In the second part, a MRF ABS test bed was built to examine the transient and steady state responses of brake in order to build mathematic brake models. The last part combined the dynamic models in the previous two parts to design an ABS Fuzzy controller. Simulation results of this controlled MRF ABS is analyzed, and experiment is also performed to verify simulation results.
