Synchronization of N different chaotic systems based on antisymmetric structure

Abstract

The problem of synchronization of N different chaotic systems is investigated. By using the direct design control method, the synchronization controler is designed to transform the error system into a nonlinear system with a special antisymmetric structure. The sufficient stability conditions are presented for such systems, and the complete synchronization of chaotic systems is realized. Finally, the corresponding numerical simulations demonstrate the effectiveness of the proposed schemes. © 2013 Xiangyong Chen and Jianlong Qiu.
