摘  要：隨著電子技術的飛速發展，電控技術在汽車上得到廣泛應用。本文針對傳統被動懸架平順性差，主動懸架成本較高的問題,提出了一種在模糊控制規則下的半主動懸架系統以實現懸架成本與性能的折中,并利用Matlab對該系統進行仿真。結果表明，應用模糊控制的半主動懸架系統可以有效提高汽車的行駛平順性并降低成本。   關鍵詞：汽車；半主動懸架；模糊控制；仿真   中圖分類號：U467.5+23 文獻標識碼：A 文章編號：1672-4984（2007）04-0060-03   Analysis of properties of semi-active suspension YI bei-hua， ZHANG Gai （National Institute of Measurment and Testing Technology，Chengdu 610021，China）   Abstract： The electronic control technology is widely used on automobile with the development of electronics. This paper discussed the bad riding comfort of traditional suspension and the high cost of active suspensions. A two-degree-freedom vehicle control of the semi-active suspensions was established and a fuzzy controller was designed in order to reach a compromise between the two problems mentioned above. This system was numerically simulated in Matlab. The results show that using fuzzy control can realize the improvement of riding comfort and reduce the cost effectively.
