| Abstract: | Synchronization of a new chaotic system is studied.Based on the nonlinear control method,three sufficient conditions of the controller for the synchronization of the chaotic systems are derived.By means of Lyapunov stabilization theorem, it is proved that global synchronization of the master and slave chaos system can be realized with the operation of the chaotic controller.Simulation test results validate the proposed synchronization methods and demonstrate its robusticity. |
