摘要
研究了Chen提出的一个新的混沌系统的混沌同步问题,利用非线性控制方法设计了三种混沌同步控制器,并用李雅普诺夫方法证明了在混沌控制器作用下,驱动、响应混沌系统可以实现全局同步.数值仿真结果表明,所设计的三种混沌控制器都能有效的实现混沌同步,并且具有很强的鲁棒性.
Synchronization of Chen chaotic system was studied. Based on nonlinear control method, three sufficient conditions of the controller for synchronization of the chaotic systems were derived. By means of Lyapunov stabilization theorem, it was proved that globally synchronization of the master and slave chaos system could be realized with the controller designed. Simulation results validated the proposed synchronization methods and showed its robusticity.
