This paper concerns the consensus of the second-order discrete-time autonomous connected vehicle system (CVS) in presence of cyber-attacks. First, the necessary and sufficient conditions for the autonomous CVS are derived without a cyber-attack. Then, a virtual system in hidden layer, interconnected with the original CVS in platoon layer through the designed interaction network, is introduced to resist cyber attacks. Matrix analysis tool, algebraic graph theory and Lyapunov stability method are used to analyze the convergence of CVS. It is proved that the states of CVS can reach consensus and the state errors converge to a certain bound in the case of attacks existing only in hidden layer, or in the overall system including both hidden layer and platoon layer. Finally, the validity of the proposed control approach is verified by the designed simulations.

具有针对网络攻击的交互网络的离散时间互联车辆系统的弹性共识
本文涉及存在网络攻击的二阶离散时间自动连接车辆系统(CVS)的共识。首先,在没有网络攻击的情况下得出了自主CVS的必要和充分条件。然后,引入隐藏层的虚拟系统,通过设计的交互网络将其与排层中的原始CVS互连,以抵御网络攻击。利用矩阵分析工具,代数图论和Lyapunov稳定性方法分析了CVS的收敛性。事实证明,仅在隐藏层或整个系统(包括隐藏层和排层)中存在攻击时,CVS的状态可以达到共识,并且状态错误收敛到一定范围。最后,
