synchronization of harb-zohdy chaotic system via back-stepping design

This paper is concerned with the problem of synchronizationof the harb-zohdy chaotic system using the back-stepping. basedon the stability theory, the control for the synchronization of chaoticsystems harb-zohdy is considered without unknown parameters. next,an adaptive back-stepping control law is derived to generate an errorsignal between the drive and response systems harb-zohdy with an uncertainparameter asymptotically synchronized. finally, this method isextended to synchronize the system with two unknown parameters.note that the method presented here needs only one controller to realizethe synchronization. numerical simulations indicate the effectiveness ofthe proposed chaos synchronization scheme.
