Abstract

Since fixed alarm thresholds fail to distinguish whether fluctuations in switched systems (SSs) are due to replay attacks (RAs) or normal switching behaviors, we propose a security control scheme. We first develop a switching-

-learning-based RA-detection method with time-varying encryption/decryption functions to learn a alarm threshold for identifying the causes of state fluctuations in SSs. Second, an RA-detection-based event-triggered mechanism is proposed, with data transmission arranged to shorten the asynchronous duration according to RA-detection results and the dissipativity level of SSs. Additionally, the cross supply rate and supply rate elucidate the impact of active and inactive subsystems on the energy dynamics of SSs under actual switching or RAs. Third, the RA-detection-based switching rule utilizes system state estimation alongside RA-detection results to address the issue of consecutive asynchronous switching caused by RAs. Finally, the security control scheme of SSs under the RA-detection is verified by studying collaborative dynamic positioning control for three unmanned surface vessels.

基于交换q -学习的重放攻击检测下带加密/解密的交换系统的耗散安全控制

由于固定的报警阈值无法区分交换系统（ss）的波动是由于重放攻击（RAs）还是正常的交换行为，我们提出了一种安全控制方案。我们首先开发了一种基于开关q学习的带有时变加密/解密功能的ra检测方法，以学习用于识别ss状态波动原因的报警阈值。其次，提出了一种基于ra检测的事件触发机制，根据ra检测结果和ss的耗散程度安排数据传输以缩短异步持续时间。此外，交叉供给率和供给率阐明了主动和非主动子系统在实际切换或RAs下对SSs能量动力学的影响。第三，基于ra检测的切换规则利用系统状态估计和ra检测结果来解决由ra引起的连续异步切换问题。最后，通过对三艘无人水面舰艇的协同动态定位控制进行研究，验证了雷达探测下SSs的安全控制方案。

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.
