Synchronization of chaotic Lur'e systems with quantized sampled-data controller

摘要

In this paper, we consider the master-slave synchronization problem of chaotic Lur'e systems. It is assumed that only quantized sampled measurements are available for the controller. By modeling the synchronization error system as an input-delay system and constructing a new Lyapunov functional, a new sufficient condition and feedback controller design method for global exponential asymptotical synchronization of master and slave system are obtained. The proposed approach has taken the feature of sample-induced delay into consideration and simulation results show the less conservativeness.
