Impulsive synchronization of Chua’s oscillators via a single variable

Impulsive synchronization of chaotic systems is an attractive topic and a number of interesting results have been obtained in recent years. However, all of the available results on impulsive synchronization need to employ full knowledge of the states of two coupled chaotic systems. In this paper, impulsive synchronization via a single variable is studied for Chua’s oscillators. Sufficient conditions for the impulsive synchronization have been analyzed theoretically and the control performance is verified by numerical simulation.
