| 摘 要： | 研究了典型混沌系统在噪声影响下的完全同步问题,包括噪声诱导同步和噪声增强同步两种情形,并以新近提出的Liu混沌系统为例进行了讨论.进一步,本文还在一般的线性耦合框架下,针对混沌系统完全同步问题,详细讨论了噪声强度和耦合强度之间的关系.研究发现:噪声强度和耦合强度两因素对于实现混沌同步均起着积极的作用.数值仿真进一步证明了这一观点.

| Abstract: | Complete synchronization phenomena between two chaotic systems under the influence of common distributed noise is investigated in this paper,including the case of noise-induced synchronization and the case of noise-enhanced synchronization.Explicit example of the newly proposed Liu chaotic system is presented for illustrations.Moreover,the relationship between the setting noise intensity and the given coupled strength against complete synchronization under traditional linear coupled scheme is also discussed in detail.Research shows that both the noise intensity and coupling strength play positive roles on chaos synchronization.The view is furtherly illustrated by numerical simulation experiments. |
