摘要

为了解决网络物理系统中基于模型的移动目标防御（MTD）方案对隐身攻击的局限性，提出了一种基于零间隙度量和稳定裕度的数据驱动移动目标防御（DD-MTD）方法。为了在数据驱动的框架中设计和实现传统的基于模型的MTD，在即插即用过程监测和控制体系结构（PnP-PMCA）下，在时域估计了-间隙度量和稳定裕度。此外，基于ν间隙度量的异常检测器有助于区分故障和隐蔽攻击。作为本研究的重要组成部分，使用实时闭环数据识别稳定图像表示（SIR）和核表示（SKR）。通过数值算例和机械轮式移动机器人的试验验证了所提方法的有效性。

A time-domain estimation of the ν-gap metric and stability margin with its application to attack defense in cyber-physical systems

To address the limitations of model-based moving target defense (MTD) scheme against stealthy attacks in cyber–physical systems, this paper proposes a novel data-driven MTD (DD-MTD)approach based on the

ν

-gap metric and the stability margin. To design and implement the traditional model-based MTD in a data-driven framework, the

ν

-gap metric and the stability margin are estimated in the time domain under the plug-and-play process monitoring and control architecture (PnP-PMCA). Besides, the anomaly detector based on the

ν

-gap metric aids in distinguishing between faults and stealthy attacks. As an essential part of this study, the stable image representation (SIR) and kernel representation (SKR) are identified using real-time closed-loop data. The proposed approaches are verified via a numerical example and a test on the Mecanum-wheeled mobile robot.

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.
