摘要
基于分数阶线性系统稳定性理论,结合反馈控制和主动控制方法,提出了一种分数阶混沌系统异结构同步方法,给出了同步控制器解析式.以分数阶Chen混沌系统和分数阶Liu混沌系统、分数阶新超混沌系统和分数阶超混沌Rssler系统的异结构同步为例,进行了数值模拟,证实了该方法的有效性和可行性.
Based on stability theory of fractional-order linear systems,a novel method combining feedback control and active control is proposed for the synchronization between two different fractional-order chaotic systems.The controller is obtained,and the method can be applied to solve synchronization problems of several classes of fractional-order chaotic systems,e.g.,Lorenz system,Rssler system,Chen system,Liu system,Lü system,Rssler hyperchaotic system and the new hyperchaotic system.Numerical simulation results are presented to demonstrate the effectiveness and feasibility of the proposed method.
