Abstract :
Chaos and its synchronization are key to chaotic secure communication. In this paper, we focus on designing an efficient synchronization controller to synchronize two Chua´s chaotic circuits with nonsmooth nonlinear term x|x|. A master-slave synchronization scheme of the interested Chua´s circuits with a simple feedback control is presented at first. Based on this scheme, some sufficient criteria for global synchronization are proved and optimized. The effectiveness of the obtained criteria is illustrated by numerical simulations.
