This paper designs four simple adaptive feedback controllers for chaos synchronization with linear– nonlinear decomposition method. Synchronization of two identical chaotic systems is realized by designed controller; Synchronization of two different chaotic systems is also realized, and the proposed method is simple and robust. Numerical simulations are given to show the effectiveness of this m...

Abstract. This paper examines the synchronization performance of two widely used chaos synchronization techniques: active control and backstepping control. It is shown that the two methods have excellent performance, with the active control marginally outperforming the backstepping control in terms of transient analysis. However, the complexity of active controllers suggests that the backsteppi...

Much research has been devoted to synchronization and chaos-based communication in the last two decades or so. Since the early 1990s, many papers have addressed the subject, and much progress has been made. Considering that the research has been developed in many different – and, at certain extent, complementary – directions, it would be interesting to outline the advances and establish the bot...

The problem of chaos synchronization is to design a coupling between two chaotic systems (master-slave/driveresponse systems configuration) such that the chaotic time evaluation becomes ideal and the output of the slave (response) system asymptotically follows the output of the master (drive) system. This paper has addressed the chaos synchronization problem of two chaotic systems using the Non...

The conventional chaos control is only to reach single control objective at each time. Different control objective only can be realized at another time. Obviously, that is not enough for applications of chaos control, especially for chaotic connected complex networks. Therefore multi-objective control (MOC) and cluster synchronization are naturally raised and deeded in practice, as well as some...

This paper studies mutually coupled integrateand-fire type chaotic oscillators. The coupling is realized by impulsive switchings and the system exhibits various synchronous and asynchronous phenomena. We give a basic classification of the chaos synchronization phenomena and their breakdown patterns. The stability of the synchronous states can be confirmed using the piecewise exact solutions, an...

This work presents two simple and robust techniques based on time delay estimation for the respective control and synchronization of chaos systems. First, one of these techniques is applied to the control of a chaotic Lorenz system with both matched and mis-matched uncertainties. The nonlinearities in the Lorenz system is cancelled by time delay estimation and desired error dynamics is inserted...

A different manner of study synchronization between chaotic systems is presented. This done by using two forced coupled nonlinear circuits. The way coupling the under from those used in analysis chaos dynamical low dimensionality. and how to manipulate it, carried out through variation couplings calculating bifurcation diagrams. We observed that for rather larger values circuits it reached tota...

Encoded information based on synchronization of coupled chaotic Nd:YAG lasers in master-slave configuration is numerically studied. Encoding, transmission, and decoding of information in optical chaotic communication with a single channel is presented. We analyze the robustness of the encrypted audio transmission in a channel noise. In order to illustrate this synchronization robustness, we pre...
