本文主要的研究為設計出一自調式灰色模糊滑動控制器作為半主動式懸吊系統之控制，其中可調式避震器屬於連續式調整，可經由轉動步進馬達達到阻尼係數的調變，可以根據不同的路面調整其軟硬度來改善車輛的舒適度，並以國際標準組織的隨機道路規格與國際糙度指標來制定出仿效真實路面的隨機測試路面訊號，藉由四分之一車懸吊系統實驗台進行實驗，實驗結果再由功率頻譜密度函數、Meister舒適度評比、加權加速度均方根值來評斷其性能表現，由實驗結果可清楚的看出自調式灰色模糊滑動控制器的設計能夠得到很好的效果及乘坐舒適性亦可以獲得改良。

This research has designed a self-tuning gray fuzzy sliding controller with an adjustable shock absorber for semi-active suspension system. A stepping motor is driven to rotate the continual adjustable shock absorber with different road. To simulate the real roads, this research formulated the signal of random road by international standard organization’s stochastic path specification and international roughness index. Power spectral density function、Meister chart and frequency weighted acceleration root-mean-square values judge the experimental performance of a quarter-car with semi-active suspension system. For the results, the self-tuning gray fuzzy sliding controller is better than another controller in riding comfort.
