摘 要：隨著電子技術(shù)的飛速發(fā)展，電控技術(shù)在汽車上得到廣泛應(yīng)用。本文針對傳統(tǒng)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(guī)則下的半主動懸架系統(tǒng)以實(shí)現(xiàn)懸架成本與性能的折中,并利用Matlab對該系統(tǒng)進(jìn)行仿真。結(jié)果表明，應(yīng)用模糊控制的半主動懸架系統(tǒng)可以有效提高汽車的行駛平順性并降低成本。 關(guān)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(xiàn)標(biāo)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.
