Synchronization of complex dynamic networks with time-varying coupled delays for sampled data control

This paper researches the synchronisation problem of complex dynamic networks with time-varying coupling delays based on sampled data control. First, a new Lyapunov-Krasovskii function (LKF) is constructed and then linear matrix inequality (LMI) is gained using Wirtinger's inequality. Then, by solving the LMI, the unconservative condition for guaranteeing the synchronisation of a time-varying coupled time delay complex network for the control of sampled data is obtained. Finally, the example of numerical simulations shows that has broad application prospects.
