中文摘要
      本文针对非结构化道路上自主卡车队列系统的控制问题进行研究, 设计一种基于级联触发的控制器,有效提高复杂工况下的卡车队列系统性能. 首先, 建立不依赖于道路结构的纵–横耦合卡车队列系统模型, 该模型涉及复杂环境下车辆存在故障(包括执行器、传感器的失效故障以及随机网络故障)影响. 其次, 为降低燃油消耗, 设计了基于自触发和事件触发的级联触发控制器, 并利用李雅普诺夫方法证明了系统的闭环稳定性. 此外, 通过对系统Zeno行为的分析量化, 得到了触发时间间隔的下界值, 保证了算法的实际应用性. 本文为了实现卡车系统队列稳定性控制目标, 进一步给出了控制器设计限制条件. 最后, 仿真结果表明, 所提出的控制方法不但能保证单车渐近稳定以及队列稳定, 还能有效减少执行器更新频率, 提高燃油经济性.
英文摘要
      In this paper, the control problem of truck platoon on unstructured roads is studied, and a controller based on cascade-trigger is designed to effectively improve the performance of the system under complex working conditions. Firstly, a longitudinal-lateral coupling truck platoon system model is established, which is independent of road structure. The model involves the influence of vehicle faults (including actuator, sensor fault and stochastic network fault) in complex environments. Secondly, in order to reduce fuel consumption, a cascade-trigger controller based on self-trigger and eventtrigger is designed, and the closed-loop stability of the system is proved by Lyapunov method. By analyzing and quantifying the Zeno behavior of the system, the lower bound of the trigger time interval is obtained, which ensures the practical application of the algorithm. In addition, the proposed controller is complemented by additional constraints to achieve string stability. Finally, the simulation results show that the proposed controller can not only ensure the individual vehicle stability and the string stability, but also reduce the frequency of actuator update and improve the fuel economy.
