模糊控制汽车ABS防抱死系统

Fuzzy controled ABS

汽车制动工况是一个非常复杂的工况，此时的汽车动力学模型几乎不可能精确建立，很难用经典控制理论实现自动控制。因此，汽车制动的优化控制一直以来为广大汽车界同行所重视。本文采用模糊控制理论，利用类似于人脑的推理方法，结合汽车理论与制动实验的经验，构造出理想的模糊控制器。使得汽车在不同的环境条件下制动时，都能使车轮处于尚未抱死而即将抱死的临界状态，缩短制动时间，减小制动距离，有效的改善了汽车的制动性能。

It's difficult to construct an exact dynamic modal of a braking automobile And this lead to the impossiblility of using classical controling methods in anti lock braking systems This paper presents the fuzzy control method By this means,the sliding coefficient is controled at the level about 20%,and we can get satisfying results
