摘要
研究了Lorenz超混沌系统的混沌同步问题,利用非线性反馈控制方法,设计了几个实现超混沌同步的控制器,结合李雅普诺夫稳定性理论证明了在混沌同步控制器作用下,驱动和相应混沌系统可以实现全局同步;数值仿真结果表明,所设计的混沌控制器能有效地实现混沌同步,并且具有很强的鲁棒性。
Synchronization of the hyperchaotic Lorenz system is studied. Based on the nonlinear feedback control method, several sufficient conditions of the controller for synchronization of the hyperchaotic Lorenz system are derived. By using the Lyapunov stabilization theorem, it is proved that global synchronization of the master and slave chaos systems can be realized with the controllers designed. Simulation results show the feasibility and robusticity of the proposed synchronization methods.
