协同自适应巡航控制系统串稳定性的多目标$H_{\infty}$控制

Multi-Objective $H_{\infty}$ Control for String Stability of Cooperative Adaptive Cruise Control Systems

Erkan Kayacan

摘要:

自动车辆跟随系统通过缩短车辆间的时间间隔,在增加道路上的车辆密度方面发挥着决定性作用。然而,沿车辆队列的干扰衰减,即,在时间间隔越来越短的情况下,串稳定性是一个具有挑战性的任务。为了保证车队的稳定性,研究了自适应巡航控制的多目标$H_{\infty}$控制方法和协同自适应巡航控制结构。所提出的控制方法解决了一个优化问题,并实现了控制器,它不仅能够提供系统的稳定性,但也从传统的$H_{\infty}$控制的字符串稳定性不同。

英文摘要:

Autonomous vehicle following systems are playing a decisive role to increase vehicle density on roads by shortening inter-vehicle time gaps. However, disturbance attenuation along a platoon of vehicles, i.e., string stability, is being a challenging task while time gap is getting shorter. In order to guarantee the string stability of a vehicle platoon, a multi-objective $H_{\infty}$ control formulation for adaptive cruise control and cooperative adaptive cruise control structures has been investigated in this paper. The proposed control method solves an optimization problem and achieves a controller that is able to provide not only the system stability, but also the string stability as distinct from the traditional $H_{\infty}$ control.
