综述汽车悬架控制系统的基本类型,以半主动悬架为研究对象,推导建立汽车两自由度1/ 4 车体模型,提出一种汽车半主动悬架系统的模糊控制方法,并利用MA TLAB 进行仿真,结果证明该控制策略有效。 关键词:汽车; 半主动悬架; 模糊控制; 仿真分析 Abstract :The paper summaries the basic types of cont rol system on automobile suspension , and taking semi2active suspension as an example , establishes a two2degree2f reedom model with a quarter of vehicle body. To the semi2active suspension system , a fuzzy cont roller is designed and is numerically simulated with MATLAB. The result s show that the fuzzy cont rol st rategy is effective.
