分数阶时滞复Lorenz混沌系统的控制与同步
Control and synchronization of fractional complex Lorenz chaotic system with time-delay
摘要
Abstract
Based on the stability theorem of the fractional nonlinear system with time-delay,the stability control of fractional chaotic system with time-delay can be realized by linear feedback controller design.Based on the method of the matrix configuration controller design,the synchronization of fractional chaotic system with unknown parameters can be realized by using the method of delay separation.This paper took fractional complex Lorenz system with time-delay as an example,seperated the real part and imaginary part of each variable of original system to study their chaotic characteristics and chaotic control.Besides,it realized chaotic system synchronization with unknown parameters of system by using matrix configuration method.Numerical simulation confirms the efficiency of the two designed controllers.关键词
