基于最佳滑移率的ABS复合控制器设计

ABS Composite Controller Design Based on Optimal Slip Ratio

针对目前的防抱制动系统(ABS)控制算法只局限于理论研究,不能在实际的ABS系统中得到应用的现状,提出了一种实用的ABS复合控制方案。研究了基于最佳滑移率的ABS控制器设计目标,提出了一种实用的鲁棒、逻辑门限复合控制方案,给出了控制器的设计方法。在单轮ABS系统上进行了试验,试验结果表明,在两种不同路面条件下,实际滑移率都能保持在最佳滑移率附近。因此,所提复合控制方案是可行和有效的。

The problem of ABS composite controller design based on optimal slip ratio is studied.The design objectives of ABS controller are proposed by taking the characteristics and the objectives of braking process into account.Then,a practical composite controller consisting of robust control and logical threshold control is presented,and the controller design approach is given.The composite controller is implemented on a single-wheel ABS system and the experiments are carried under two kinds of road conditions.The experimental results show that the actual slip ratio is kept near the optimal slip ratio under the composite controller.Thus,the proposed composite controller is feasible and valid.
