Abstract

In this paper, we focus on developing a resilient stepped transmission scheme for nonlinear networked systems suffering from Denial-of-Service (DoS) attacks. Instead of employing static periodic sampling, the proposed acknowledgement-based adaptive sampler follows a resilient stepped algorithm to dynamically adjust the sampling period based on the absence or presence of DoS attacks. The dynamic sampling period is demonstrated to approach the boundary sampling interval to better adapt to the vulnerable environment, where the boundary sampling interval is the largest sampling period to ensure the boundedness of successful transmission interval in conventional periodic sampling scheme. Two impulsive observer-based control structures are presented to ensure the asymptotic stability of the equilibrium of systems, in which the latter one can better cope with the amplification of observer error in the presence of DoS. Numerical simulations are given finally to substantiate the validity of theoretical results.

针对 DoS 攻击的非线性系统弹性阶跃传输和控制

在本文中，我们重点针对遭受拒绝服务（DoS）攻击的非线性网络系统开发了一种弹性阶跃传输方案。所提出的基于确认的自适应采样器不采用静态周期采样，而是采用弹性阶梯算法，根据是否存在 DoS 攻击动态调整采样周期。动态采样周期接近边界采样间隔，能更好地适应易受攻击的环境，而边界采样间隔是最大的采样周期，可确保传统定期采样方案中成功传输间隔的有界性。提出了两种基于脉冲观测器的控制结构，以确保系统平衡的渐近稳定性，其中后一种结构能更好地应对 DoS 存在时观测器误差的放大。最后给出了数值模拟，以证实理论结果的正确性。

期刊介绍： Automatica is a leading archival publication in the field of systems and control. The field encompasses today a broad set of areas and topics, and is thriving not only within itself but also in terms of its impact on other fields, such as communications, computers, biology, energy and economics. Since its inception in 1963, Automatica has kept abreast with the evolution of the field over the years, and has emerged as a leading publication driving the trends in the field. After being founded in 1963, Automatica became a journal of the International Federation of Automatic Control (IFAC) in 1969. It features a characteristic blend of theoretical and applied papers of archival, lasting value, reporting cutting edge research results by authors across the globe. It features articles in distinct categories, including regular, brief and survey papers, technical communiqués, correspondence items, as well as reviews on published books of interest to the readership. It occasionally publishes special issues on emerging new topics or established mature topics of interest to a broad audience. Automatica solicits original high-quality contributions in all the categories listed above, and in all areas of systems and control interpreted in a broad sense and evolving constantly. They may be submitted directly to a subject editor or to the Editor-in-Chief if not sure about the subject area. Editorial procedures in place assure careful, fair, and prompt handling of all submitted articles. Accepted papers appear in the journal in the shortest time feasible given production time constraints.
