Synchronization for time-varying complex networks based on control

In this paper, the problem on synchronization is investigated for complex networks with time-varying delay and without time-varying delay by using control strategy. Together with some Lyapunov–Krasovskii functions and effective mathematical techniques, several conditions are derived to guarantee a class of complex networks with time-varying and without time-varying delays to be synchronized. Finally, examples are given to illustrate the effectiveness of the proposed methods.
