提出了一类混沌系统的观测器同步方法。利用混沌系统的不确定项观测器,给出了一类混沌系统基于观测器同步的简单有效方法,该方法不需知道外部扰动的任何信息,且观测器的设计方法简单,利于工程应用。通过对Lorenz混沌系统的分析和数值模拟研究,验证了该方法在混沌同步中的优良性能。
A simple but effective method was proposed for synchronization of a class of chaotic systems of uncertainness observer. The method needed no information about the external perturbation, and the by use design method of the observer was simple, which made it easy for engineering application. Numerical simulation was made to Lorenz chaotic system, which verified the fine performance of the method in chaotic synchronization.
