Abstract

This article discusses finite-time lag bipartite (FETLB) synchronization of double-layer networks with non-linear coupling strength and multiple time delays. The cooperative and competitive interactions between nodes are considered based on signed graphs. To address the non-linear couplings strength, the T-S fuzzy logic theory is used. An intermittent control approach is introduced to achieve FETLB synchronization, effectively minimizing control costs. Moreover, by the Lyapunov functional method, we derive criteria for achieving FETLB synchronization and provide estimations for the synchronization settling time. In addition, numerical simulation affirms the validity of the theoretical findings, showcasing the practical application of the synchronization results in secure communication.

通过 T-S 模糊逻辑理论实现具有非线性耦合强度和随机耦合延迟的双层网络的有限时滞双网同步

本文讨论了具有非线性耦合强度和多时间延迟的双层网络的有限时滞双网同步（FETLB）问题。基于符号图考虑了节点间的合作和竞争交互。为解决非线性耦合强度问题，采用了 T-S 模糊逻辑理论。为实现 FETLB 同步，引入了一种间歇控制方法，有效地降低了控制成本。此外，通过 Lyapunov 函数方法，我们得出了实现 FETLB 同步的标准，并提供了同步稳定时间的估计值。此外，数值模拟证实了理论结论的正确性，展示了同步结果在安全通信中的实际应用。

期刊介绍： IET Control Theory & Applications is devoted to control systems in the broadest sense, covering new theoretical results and the applications of new and established control methods. Among the topics of interest are system modelling, identification and simulation, the analysis and design of control systems (including computer-aided design), and practical implementation. The scope encompasses technological, economic, physiological (biomedical) and other systems, including man-machine interfaces. Most of the papers published deal with original work from industrial and government laboratories and universities, but subject reviews and tutorial expositions of current methods are welcomed. Correspondence discussing published papers is also welcomed. Applications papers need not necessarily involve new theory. Papers which describe new realisations of established methods, or control techniques applied in a novel situation, or practical studies which compare various designs, would be of interest. Of particular value are theoretical papers which discuss the applicability of new work or applications which engender new theoretical applications.
