A New 3D Autonomous Continuous System with Two Isolated Chaotic Attractors and Its Topological Horseshoes

open access: yesComplexity, 2017
Based on the 3D autonomous continuous Lü chaotic system, a new 3D autonomous continuous chaotic system is proposed in this paper, and there are coexisting chaotic attractors in the 3D autonomous continuous chaotic system.

Entropy Analysis and Image Encryption Application Based on a New Chaotic System Crossing a Cylinder

open access: yesEntropy, 2019
Designing chaotic systems with specific features is a hot topic in nonlinear dynamics. In this study, a novel chaotic system is presented with a unique feature of crossing inside and outside of a cylinder repeatedly.

Learning Chaotic Attractors by Neural Networks [PDF]

open access: yesNeural Computation, 2000
An algorithm is introduced that trains a neural network to identify chaotic dynamics from a single measured time series. During training, the algorithm learns to short-term predict the time series. At the same time a criterion, developed by Diks, van Zwet, Takens, and de Goede (1996) is monitored that tests the hypothesis that the reconstructed ...

Variations of Boundary Surface in Chua’s Circuit [PDF]

open access: yes, 2015
The paper compares the boundary surfaces with help of cross-sections in three projection planes, for the four changes of Chua’s circuit parameters. It is known that due to changing the parameters, the Chua’s circuit can be characterized in addition to a ...

On the boundary crises of chaotic attractors in nonlinear oscillators

open access: yesComputer Assisted Methods in Engineering and Science, 2023
In nonlinear dissipative mechanical systems, bifurcations of chaotic attractors called boundary crises appear to be the cause of most sudden changes in chaotic dynamics.

Dominant Attractor in Coupled Non-Identical Chaotic Systems

open access: yesEntropy, 2022
The dynamical interplay of coupled non-identical chaotic oscillators gives rise to diverse scenarios. The incoherent dynamics of these oscillators lead to the structural impairment of attractors in phase space.

Optimal fluctuations and the control of chaos. [PDF]

open access: yes, 2002
The energy-optimal migration of a chaotic oscillator from one attractor to another coexisting attractor is investigated via an analogy between the Hamiltonian theory of fluctuations and Hamiltonian formulation of the control problem.

Digital Communication Systems Based on Three-Dimensional Chaotic Attractors

open access: yesIEEE Access, 2019
In this paper, we propose a methodology to design chaos-based communication systems, which exploits the topological structure of 3-D chaotic attractors. The first step consists in defining a proper partition of a Poincaré section of the attractor
