Abstract

This work deals with the synchronization problem of complex dynamical networks (CDNs) with additive time-varying delays. To attain the desired result, an effective uncertainty and disturbance estimator (UDE)-based fault-tolerant controller with deception attacks technique is developed to overcome the obstacles. A Bernoulli random variable is employed to find the success ratio of deception attacks. By designing a suitable Lyapunov–Krasovskii functional (LKF) and utilizing Jensen’s inequality, a sufficient condition is expressed in the form of a linear matrix inequality (LMI) to ensure the asymptotic synchronization of the proposed model. Based on the UDE approach, the effects of unknown system uncertainty and external disturbance are nullified by introducing an appropriate filter. Finally, two numerical examples are presented to demonstrate the significance and applicability of the theoretical results.

这项研究涉及具有时变延迟加法的复杂动态网络（CDN）的同步问题。为了达到预期结果，开发了一种基于不确定性和干扰估计器（UDE）的有效容错控制器，并采用欺骗攻击技术来克服障碍。采用伯努利随机变量来计算欺骗攻击的成功率。通过设计合适的 Lyapunov-Krasovskii 函数（LKF）并利用詹森不等式，以线性矩阵不等式（LMI）的形式表达了一个充分条件，以确保所提模型的渐进同步性。基于 UDE 方法，通过引入适当的滤波器，可以消除未知系统不确定性和外部干扰的影响。最后，介绍了两个数值示例，以证明理论结果的意义和适用性。

期刊介绍： The European Control Association (EUCA) has among its objectives to promote the development of the discipline. Apart from the European Control Conferences, the European Journal of Control is the Association''s main channel for the dissemination of important contributions in the field. The aim of the Journal is to publish high quality papers on the theory and practice of control and systems engineering. The scope of the Journal will be wide and cover all aspects of the discipline including methodologies, techniques and applications. Research in control and systems engineering is necessary to develop new concepts and tools which enhance our understanding and improve our ability to design and implement high performance control systems. Submitted papers should stress the practical motivations and relevance of their results. The design and implementation of a successful control system requires the use of a range of techniques: Modelling Robustness Analysis Identification Optimization Control Law Design Numerical analysis Fault Detection, and so on.
