A chaotic masking scheme by using synchronized chaotic systems
(Elsevier, 1999)We present a new chaotic masking scheme by using synchronized chaotic systems. In this method, synchronization and message transmission phases are separated, and while synchronization is achieved in the synchronization ... 
Further stability results for a generalization of delayed feedback control
(Springer, 20120801)In this paper, we consider the stabilization of unstable periodic orbits for onedimensional and discrete time chaotic systems. Various control schemes for this problem are available and we consider a recent generalization ... 
Model based anticontrol of chaos
(IEEE, 2003)We will consider model based anticontrol of chaotic systems. We consider both continuous and discrete time cases. We first assume that the systems to be controlled are linear and time invariant. Under controllability ... 
Model based anticontrol of discretetime systems
(IEEE, 2003)We will consider a modelbased approach for the anticontrol of some discretetime systems. We first assume the existence of a chaotic model in an appropriate form. Then by using an appropriate control input we try to match ...

A new periodic controller for discrete time chaotic systems
(IFAC, 2010)In this paper we consider the stabilization problem of unstable periodic orbits of discrete time chaotic systems. For simplicity we consider only one dimensional case. We propose a novel periodic feedback controller law ... 
A nonlinear control scheme for discrete time chaotic systems
(The International Federation of Automatic Control, 201206)In this paper we consider the stabilization problem of unstable periodic orbits of discrete time chaotic systems. We consider both one dimensional and higher dimensional cases. We propose a nonlinear feedback law and present ... 
Observer based chaotic message transmission
(World Scientific Publishing, 2003)We consider observer based synchronization of continuoustime chaotic systems. We present two message transmission schemes for such systems. The first one is based on chaotic masking and modulation, and the second one is ... 
Observerbased control of a class of chaotic systems
(Elsevier, 2001)We consider the control of a class of chaotic systems, which covers the forced chaotic oscillators. We focus on two control problems. The first one is to change the dynamics of the system to a new one which exhibits a ... 
On the stability of delayed feedback controllers
(Elsevier, 2003)We consider the stability of delayed feedback control (DFC) scheme for onedimensional discrete time systems. We first construct a map whose fixed points correspond to the periodic orbits of the uncontrolled system. Then ...

On the synchronization of logistic maps
(Elsevier BV, 19981026)We study the synchronization of two chaotic maps described by a logistic equation. We propose a new feedback term and show that the resulting system has some desired properties including exponential synchronization with ... 
Stabilization of unstable periodic orbits for discrete time chaotic systems by using periodic feedback
(World Scientific Publishing, 2006)We propose a periodic feedback scheme for the stabilization of periodic orbits for discrete time chaotic systems. We first consider onedimensional discrete time systems and obtain some stability results. Then we extend ... 
Synchronization of chaotic systems by using occasional coupling
(Bilkent University, 1997)Nonlinear and chaotic systems are difficult to control due to their unstable and unpredictable nature. Although, much work has been done in this area, synchronization of chaotic systems still remains a worthwhile ... 
Watermarking based on discrete wavelet transform and qdeformed chaotic map
(Elsevier Ltd, 2017)Hierarchy of onedimensional ergodic chaotic maps with Tsallis type of qdeformation are studied. We find that in the chaotic region, these maps with qdeformation are ergodic as the Birkhoff ergodic theorem predicts. ...
