异结构离散型混沌系统的延迟同步

Lag Synchronization Between Discrete Chaotic Systems With Diverse Structure

以异结构离散型混沌系统为研究对象,设计了一种延迟同步控制器实现了离散型Henon混沌系统和Ikeda混沌系统之间的同步控制.根据稳定性定理,确定了延迟同步控制器的结构以及系统状态变量之间的误差方程.设计的延迟同步控制器对于不同的离散型混沌系统具有统一的形式,可以实现任意异结构离散型混沌系统之间的延迟同步.数值仿真模拟进一步验证了该控制器的有效性.

A lag synchronization controller was designed to discuss discrete chaotic systems with diverse structures and to realize synchronization between＇Henon system and Ikeda system. The structure of the lag synchronization controller and the error equations of state variables between discrete chaotic systems were presented on the basis of stability theory. The designed controller had unique structures for different chaotic systems, and lag synchronization between any discrete chaotic systems with diverse structures could be achieved. The artificial simulation results show that this control method is effective and feasible.
