چکیده
|
Synchronization of two chaotic systems has been used in secure communications.in this paper, synchronization of two identical 4d lu hyper-chaotic systems is usedto identify the drive system. parameters in both drive and response systems are unknownand the systems are synchronized by applying one state feedback controller. since the goalhere is to identify the parameters of the drive system, an adaptive method is used. thestability of the closed-loop system with the controller and convergence of parameters isstudied using the lyapunov theorem. in order to improve the speed of convergence in oneparameter, a fractional adaptation law is used and the stability with the fractional law isshown. finally, the results of both integer and fractional methods are compared.
