Synchronization for multiple coupled chaotic systems with unknown parameters

摘要

This paper studies the transmission synchronization (TS) problem among multiple coupled chaotic systems by considering unknown parameters. In the solving process, we firstly select a special integral sliding surfaces, and then we develop an effective controller with the compensation terms to guarantee the asymptotical stability of all TS error systems. Simultaneously, we design the proper adaptive laws to estimate all unknown parameters. Finally, numerical example is used to show the effectiveness of the proposed schemes.
