联网和自动驾驶车辆 (CAV) 的排队预计将对道路交通产生变革性影响,例如增强高速公路安全、改善交通实用性和减少燃料消耗。分布式控制方案仅需要本地信息,是协调多个 CAV 的可扩展方法,无需使用集中式通信和计算。本文从多智能体共识控制的角度出发,引入分解框架对排系统进行建模、分析和设计。在这个框架中,排自然地分解为四个相互关联的组件,即1)节点动态,2)信息流网络,3)分布式控制器和4)几何结构。根据文献调查结果总结出各组件的经典模型;以相同的方式讨论了四个主要性能指标,即内部稳定性、稳定性裕度、弦稳定性和相干性行为。此外,还介绍了典型分布式控制技术的基础,包括线性一致控制、分布式鲁棒控制、分布式滑模控制和分布式模型预测控制。
The platooning of connected and automated vehicles (CAVs) is expected to have a transformative impact on road transportation, e.g., enhancing highway safety, improving traffic utility, and reducing fuel consumption. Requiring only local information, distributed control schemes are scalable approaches to the coordination of multiple CAVs without using centralized communication and computation. From the perspective of multi-agent consensus control, this paper introduces a decomposition framework to model, analyze, and design the platoon system. In this framework, a platoon is naturally decomposed into four interrelated components, i.e., 1) node dynamics, 2) information flow network, 3) distributed controller, and 4) geometry formation. The classic model of each component is summarized according to the results of the literature survey; four main performance metrics, i.e., internal stability, stability margin, string stability, and coherence behavior, are discussed in the same fashion. Also, the basis of typical distributed control techniques is presented, including linear consensus control, distributed robust control, distributed sliding mode control, and distributed model predictive control.
