Finite-time synchronization of a class of uncertain complex dynamic networks with delays

Abstract

This study investigated finite-time synchronization of uncertain nonlinear complex dynamic network with delays. For a class of complex network models with delays and uncertain system parameters, uncertain terms are unknown but bounded, and the matching conditions are satisfied. The coupling relationship between the nodes is a nonlinear function with time delay, and the function satisfies Lipschitz condition. A new criterion for the finite-time synchronization of a class of complex dynamic networks with delay and uncertainty is obtained, and the upper bound of the time for the system to achieve synchronization is presented. Meanwhile, some numerical examples are given to verify the feasibility of the results.
