Abstract:

A non-fragile synchronization approach is proposed for a time-varying complex dynamical network via state feedback control. Under the assumptions that uncertainty of the weight matrix of the complex network is bounded and the norm of the perturbation of internal coupled matrix is bounded, the additive and product non-fragile feedback control algorithms are designed and the sufficient conditions for the synchronization of the complex dynamical network are presented in terms of LMIs, respectively. An example is given to show the effectiveness of the algorithm.

Key words: complex dynamical networks, synchronization, non-fragile control, linear maxtrix inequality, Lyapunov function
