Synchronicity from Synchronized Chaos [PDF]

Entropy, 2015
The synchronization of loosely-coupled chaotic oscillators, a phenomenon investigated intensively for the last two decades, may realize the philosophical concept of “synchronicity”—the commonplace notion that related eventsmysteriously occur at the same time.

Parameter mismatches,variable delay times and synchronization in time-delayed systems [PDF]

, 2004
We investigate synchronization between two unidirectionally linearly coupled chaotic non-identical time-delayed systems and show that parameter mismatches are of crucial importance to achieve synchronization. We establish that independent of the relation

Synchronization of the Fractional-Order Brushless DC Motors Chaotic System

Journal of Control Science and Engineering, 2016
Based on the extension of Lyapunov direct method for nonlinear fractional-order systems, chaos synchronization for the fractional-order Brushless DC motors (BLDCM) is discussed. A chaos synchronization scheme is suggested.

Symplectic Synchronization of Lorenz-Stenflo System with Uncertain Chaotic Parameters via Adaptive Control

Abstract and Applied Analysis, 2013
A new symplectic chaos synchronization of chaotic systems with uncertain chaotic parameters is studied. The traditional chaos synchronizations are special cases of the symplectic chaos synchronization. A sufficient condition is given for the asymptotical

Study on Super-Twisting synchronization control of chaotic system based on U model

Journal of Hebei University of Science and Technology, 2016
A U model based Super-Twisting synchronization control method for chaotic systems is proposed. The chaos control of chaotic systems is prescribed, then, based on the current research status of chaotic systems and some useful research results in nonlinear

Observer-Based Finite-Time Modified Projective Synchronization of Multiple Uncertain Chaotic Systems and Applications to Secure Communication Using DNA Encoding

IEEE Access, 2019
This paper studies an observer-based finite-time scheme for two modified projective synchronization modes, including the synchronization of multiple uncertain chaotic response systems to one drive system and transmission synchronization.

Dynamic multi‐objective optimisation of complex networks based on evolutionary computation

IET Networks, EarlyView., 2022
Abstract As the problems concerning the number of information to be optimised is increasing, the optimisation level is getting higher, the target information is more diversified, and the algorithms are becoming more complex; the traditional algorithms such as particle swarm and differential evolution are far from being able to deal with this situation ...
