Finite-time synchronization of uncertain fractional-order multi-weighted complex networks with external disturbances via adaptive quantized control

Abstract

In this paper, finite-time synchronization of fractional-order multi-weighted complex networks (FMCNs) with uncertain parameters and external disturbances is studied. Firstly, based on fractional calculus characteristics and Lyapunov stability theory, quantized controllers are designed to guarantee that FMCNs can achieve synchronization in a limited time with and without coupling delay respectively. Then, appropriate parameter update laws are obtained to identify uncertain parameters in FMCNs. Finally, numerical simulation examples are given to validate the correctness of the theoretical results.
