关于主-从混沌蔡氏电路系统滞后同步的若干新判据

The novel criteria for lag synchronization of the master-slavechaotic Chua's circuits

研究主-从蔡氏电路(Chua’s Circuits)系统在线性状态误差反馈控制下存在通道时延时的滞后混沌同步问题。运用多项式理论中的斯图姆定理和因式分解定理等工具,严格证明了几种控制增益矩阵情形下的代数型滞后混沌同步判据,并通过与现有文献同类判据的实例比较,验证了这些新判据具有更少的保守性。

The lag synchronization of the master-slave chaotic Chuas circuits via linback control with the channel delay is studied. Several algebraic criteria for thetion subject to the special control gain matrices are rigorously proven by factorization theorem in polynomial theory. It is verified by comparison of the numerical examples withsuch criteria existing in the literature that the new criteria are less conservative.
