Abstract

This paper deals with the synchronization stability and control problems for neutral-type complex dynamical network with interval time-varying coupling delay. By dividing the delay interval into two equidistant subintervals and constructing two appropriate Lyapunov–Krasovskii functionals, several less conservative delay-dependent synchronization stability criteria are proposed in terms of linear matrix inequalities. Furthermore, a simple linear state feedback controller is introduced to force the network to synchronize, while the whole network cannot achieve synchronization by itself. Some sufficient synchronization conditions for the controlled network are derived. The minimum feedback gain can be determined based on the proposed conditions. Numerical examples are given to demonstrate the effectiveness and less conservatism of the proposed method.
