DYNAMICS, ADAPTIVE CONTROL AND EXTENDED SYNCHRONIZATION OF HYPERCHAOTIC SYSTEM AND ITS APPLICATION TO SECURE COMMUNICATION Onma O. S1 and Akinlami J.O2 1Nonlinear Dynamics Research Group, Department of Physics, Federal University of Agriculture, Abeokuta, Nigeria 2Department of Physics, Federal University of Agriculture Abeokuta, Nigeria ABSTRACT This work studies the dynamics, control and synchronization of hyperchaotic Lorenz-stenflo system and its application to secure communication. The proposed designed nonlinear feedback controller control and globally synchronizes two identical Lorenz-stenflo hyperchaotic systems evolving from different initial conditions with unknown parameters. Adaptive synchronization results were further applied to secure communication. The numerical simulation results were presented to verify the effectiveness of the designed nonlinear controller and its success in secure communication application.

Synchronization and Inverse Synchronization of Some Different Dimensional Discrete-time Chaotic Dynamical Systems via Scaling Matrices   Adel Ouannas  LAMIS Laboratory, Department of Mathematics and Computer Science, University of Tebessa, 12002, Algeria.  Abstract  In this paper, new types of synchronization and inverse synchro-nization are proposed for some di¤erent dimensional chaotic dynamical systems in discrete-time using scaling matrices. Based on Lyapunov stability theory and nonlinear controllers, new synchronization results are derived. Numerical simulations are used to verify the e¤ectiveness of the proposed schemes.  Keyword  Synchronization, inverse synchronization, chaotic dynamical sys-tems, discrete-time, Lyapunov stability  Original Source URL :   http://airccse.org/journal/ijccms/papers/3414ijccms01.pdf http://airccse.org/journal/ijccms/current2014.html
