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

• A quantized sampled-data synchronization approach for Lur’e systems is proposed.
• Full information of sample-induced delay is considered in the Lyapunov functional.
• A new sufficient condition and feedback controller design method are obtained.
• We show the less conservativeness compared with the existing results.

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.
