论文摘要
这封信涉及量化网络控制系统（NCSS）的弹性弹性（DOS）攻击和可变网络延迟的问题。研究了内部指数稳定性和$ \ MATHCAL {L} _2 $外部稳定性。闭环系统通过辅助计时器变量增强，并在混合系统框架中进行分析。提供类似Lyapunov的条件，以确保$ 0 $ -INPUT全局指数稳定性和$ \ Mathcal {L} _2 $外部稳定性。设计了基于线性矩阵不等式的计算负担得起的算法，以在DOS攻击的最大长度和最大的网络延迟之间提供权衡曲线。最后，在数值示例中显示了所提出的方法的有效性。
This letter deals with the problem of quantifying resiliency of Networked Control Systems (NCSs) to Denial-of-Service (DoS) attacks and variable network delays. Internal exponential stability and $\mathcal{L}_2$ external stability are studied. The closed-loop system is augmented with an auxiliary timer variable and analyzed in a hybrid system framework. Lyapunov-like conditions are given to ensure $0$-input global exponential stability and $\mathcal{L}_2$ external stability. A computationally affordable algorithm based on linear matrix inequalities is devised to provide trade-off curves between maximum length of DoS attacks and largest network delays. Finally, the effectiveness of the proposed approach is shown in a numerical example.
