Event-dependent intermittent synchronization of complex networks based on discrete-time state observation

Abstract

This paper studies the synchronization issue of complex networks via event-dependent intermittent discrete-time observation control (EIDOC) for the first time. Three non-negative real domains are characterized by introducing two boundary functions. The work and rest time of intermittent control rely on the relationship between the Lyapunov function trajectory and non-negative regions. The proposed aperiodically intermittent control is based on discrete-time state observation rather than continuous observation during the work interval. Some sufficient criteria are derived for ensuring synchronization of the network. The theoretical results are employed to deal with single pendulum systems, and numerical simulation have demonstrated the effectiveness of the derived method.
