摘要:

本文介绍了一种新颖的基于延迟的间距策略用于车辆车群控制,并提出了扰动字符串稳定性的概念。该策略规定车辆间的期望间距,并保证所有车辆跟踪相同空间变化的参考速度剖面,如重型车辆在起伏地形驾驶时所需。扰动字符串稳定性是车辆车群在所有车辆受外部扰动时的字符串稳定性概念,保证扰动在传播过程中不无界增长。具体而言,提出了一种空间域的控制设计方法,实现对期望间距策略的跟踪并保证对空间变化参考速度的扰动字符串稳定性。结果通过仿真进行说明。

英文摘要:

A novel delay-based spacing policy for the control of vehicle platoons is introduced together with a notion of disturbance string stability. The delay-based spacing policy specifies the desired inter-vehicular distance between vehicles and guarantees that all vehicles track the same spatially varying reference velocity profile, as is for example required for heavy-duty vehicles driving over hilly terrain. Disturbance string stability is a notion of string stability of vehicle platoons subject to external disturbances on all vehicles that guarantees that perturbations do not grow unbounded as they propagate through the platoon. Specifically, a control design approach in the spatial domain is presented that achieves tracking of the desired spacing policy and guarantees disturbance string stability with respect to a spatially varying reference velocity. The results are illustrated by means of simulations.
