Abstract

This paper focuses on the investigation of fixed-time synchronization in intermittently coupled complex networks that exhibit coupling delay. A novel fixed-time stability lemma is introduced, which encompasses complete aperiodic intermittent characteristics and has a more straightforward formulation relative to prior research. An economical intermittent controller is designed based on the concept of the average control rate. Employing Lyapunov stability theory, adequate criteria are established to guarantee fixed-time synchronization of dynamical networks. Ultimately, numerical simulations are performed to demonstrate the effectiveness and practicality of the proposed methodologies.

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.
