摘要

详细介绍了一种确定两个相同或不匹配混沌系统工程同步状态的方法。针对混合同步、线性和非线性广义同步以及定点瞄准等工程同步问题,提出了采用线性反馈控制器耦合的方法。利用李雅普诺夫函数稳定性理论,解析导出了在单向耦合下,针对任意期望同步状态的耦合设计的一般形式。在耦合定义中引入了一个比例因子来平滑控制而不丢失同步。在两个不匹配的洛伦兹系统和两个相同的斯普罗特振子上进行了数值计算。

Targeting engineering synchronization in chaotic systems
A method of targeting engineering synchronization states in two identical and mismatch chaotic systems is explained in details. The method is proposed using linear feedback controller coupling for engineering synchronization such as mixed synchronization, linear and nonlinear generalized synchronization and targeting fixed point. The general form of coupling design to target any desire synchronization state under unidirectional coupling with the help of Lyapunov function stability theory is derived analytically. A scaling factor is introduced in the coupling definition to smooth control without any loss of synchrony. Numerical results are done on two mismatch Lorenz systems and two identical Sprott oscillators.
