ABS智能控制器的设计与仿真

Designing and simulation of ABS intelligent controller

车辆ABS(Antilock Braking System)智能控制是一种优于传统ABS控制的控制技术,能够将车轮滑移率控制在目标滑移率附近,并且自动识别道路附着状况搜索最佳滑移率值,达到利用路面最大附着力的自适应效果。在建立车辆单轮防抱死仿真系统的基础上,设计了一个基于最佳滑移率的积分分离PID自适应控制器,并分别对此进行数字仿真与实物实验,结果表明,该控制器的控制稳定性、鲁棒性和自适应性均取得了良好的效果。

The vehicle ABS intelligent control is a control technology that is more advanced than traditional ABS control method. It can control the slip rate stable around the target slip ratio and identify the road characteristics automatically to get the best braking effect. On the establishment of a single wheel of vehicle ABS system, this paper designed an optimal sliding rate integral separate PID self-adaptive controller. Simulation and real experiment were conducted. The experiment results showed that the control stability, robust and adaptability were effective.
