On Synchronization With Positive Conditional Lyapunov Exponents
نویسنده
چکیده
Synchronization of chaotic system may occur only when the largest conditional Lyapunov exponent of the driven system is negative. The synchronization with positive conditional Lyapunov reported in a recent paper (Phys. Rev. E, 56, 2272 (1997)) is a combined result of the contracting region of the system and the finite precision in computer simulations. PACS number(s): 05.45.+b;

Exploiting the Concept of Conditional Transversal Lyapunov Exponents for Study of Synchronization of Chaotic Circuits
| The problem of synchronization of coupled chaotic systems is considered. The notion of local transversal Lyapunov exponents is introduced. We show that they can be successfully used in investigations of the synchronization properties. The technique is illustrated with computer simulations.
متن کاملLyapunov exponents, noise-induced synchronization, and Parrondo's paradox.
We show that Lyapunov exponents of a stochastic system, when computed for a specific realization of the noise process, are related to conditional Lyapunov exponents in deterministic systems. We propose to use the term stochastically induced regularity instead of noise-induced synchronization and explain the reason why. The nature of stochastically induced regularity is discussed: in some instan...
متن کاملConditional exponents, entropies and a measure of dynamical self-organization
In dynamical systems composed of interacting parts, conditional exponents, conditional exponent entropies and cylindrical entropies are shown to be well defined ergodic invariants which characterize the dynamical selforganization and statitical independence of the constituent parts. An example of interacting Bernoulli units is used to illustrate the nature of these invariants. 1 Conditional exp...
متن کاملDynamical behavior and synchronization of hyperchaotic complex T-system
In this paper, we introduce a new hyperchaotic complex T-system. This system has complex nonlinear behavior which we study its dynamical properties including invariance, equilibria and their stability, Lyapunov exponents, bifurcation, chaotic behavior and chaotic attractors as well as necessary conditions for this system to generate chaos. We discuss the synchronization with certain and uncerta...
متن کاملStudy of Synchronization of Linearly Coupled Hyperchaotic Systems
In this paper we report results on synchronization of two simple four-dimensional hyperchaotic electronic circuit by means of the linear coupling method. We prove analytically that using appropriate coupling these hyperchaotic systems synchronizes for all initial conditions. In simulations we observe that synchronization is also possible when the systems are coupled using only one variable. Thi...
