摘要: 为了解决通信拓扑随机切换、信息时延和外部干扰下的队列系统稳定性控制问题,提出一种基于事件触发机制的鲁棒控制策略。基于有向图理论建立通信结构切换下的马尔可夫跳跃拓扑模型,同时将对队列稳定性影响巨大的外界随机风速扰动、数据丢包与信息时滞、车载传感器数据离散化特性等因素整合到队列中,构建通信拓扑结构随机切换下的异质多车队列模型。为了保证队列系统的内稳定性,根据H控制和马尔可夫跳跃系统的稳定性理论,提出一种基于事件触发机制的分布式随机稳定鲁棒控制方法。此外,还给出了L2随机队列稳定性的定义,以减小扰动在整个队列中的扩散。试验结果表明,在通信拓扑随机切换、信息时延和外部干扰下,与传统队列鲁棒控制方法相比,所提出控制方法可以获得更小的相邻车间距和速度跟踪误差,同时能够以较低的计算负荷实现队列系统的稳定性。

Abstract: To resolve the vehicle platoon’s random change of communication topologies, information delay, and outside disturbance, a robust event-triggered control protocol based on the discrete event-triggered communication scheme is proposed. The Markov chain combined with directed graph approach is used to describe the platoon’s random switching data transmission network in actual traffic. The effects of delays and air resistance of the platooning system is investigated under equivalent information delays and outside interferences. To guarantee the inner-vehicle stability of the platooning system, the distributed controller with variable gains based on event-triggered scheme is put forward according to H control and the stability theory of Markovian jumping system. In addition, the definition of L2 stochastic string stability is also given out to reduce perturbations when they spread throughout the platoon. Compared to traditional platoon robust control, it is shown that the proposed controller can obtain smaller adjacent spacing and speed tracking errors, and evenly realize the vehicle platoon’s stability with a lower computing burden.

Key words: vehicle platoon, random switching topologies, external disturbance, string stability, event-triggered control
