Hidden Bifurcations in the Multispiral Chua Attractor [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2016
We introduce a novel method revealing hidden bifurcations in the multispiral Chua attractor in the case where the parameter of bifurcation [Formula: see text] which determines the number of spiral is discrete. This method is based on the core idea of the genuine Leonov and Kuznetsov method for searching hidden attractors (i.e.

Approximating hidden chaotic attractors via parameter switching [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2018
In this paper, the problem of approximating hidden chaotic attractors of a general class of nonlinear systems is investigated. The parameter switching (PS) algorithm is utilized, which switches the control parameter within a given set of values with the initial value problem numerically solved.

A New Fractional-Order Chaotic System with Different Families of Hidden and Self-Excited Attractors

open access: yesEntropy, 2018
In this work, a new fractional-order chaotic system with a single parameter and four nonlinearities is introduced. One striking feature is that by varying the system parameter, the fractional-order system generates several complex dynamics: self-excited ...

Smoothing tautologies, hidden dynamics, and sigmoid asymptotics for piecewise smooth systems [PDF]

open access: yes, 2015
Switches in real systems take many forms, such as impacts, electronic relays, mitosis, and the implementation of decisions or control strategies. To understand what is lost, and what can be retained, when we model a switch as an instantaneous event ...

Generating Any Number of Diversified Hidden Attractors via Memristor Coupling

open access: yesIEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2021
Memristors are widely used to construct multi-scroll/wing chaotic systems with complex dynamics. However, the generation of a multi-scroll/wing attractor is typically not induced by the memristor but depends on other nonlinear functions in the system ...

Poincaré maps for detecting chaos in fractional-order systems with hidden attractors for its Kaplan-Yorke dimension optimization

open access: yesAIMS Mathematics, 2022
The optimization of fractional-order (FO) chaotic systems is challenging when simulating a considerable number of cases for long times, where the primary problem is verifying if the given parameter values will generate chaotic behavior.

Hold-in, pull-in, and lock-in ranges of PLL circuits: rigorous mathematical definitions and limitations of classical theory [PDF]

open access: yes, 2015
The terms hold-in, pull-in (capture), and lock-in ranges are widely used by engineers for the concepts of frequency deviation ranges within which PLL-based circuits can achieve lock under various additional conditions. Usually only non-strict definitions

A Symmetric Controllable Hyperchaotic Hidden Attractor [PDF]

open access: yesSymmetry, 2020
By introducing a simple feedback, a hyperchaotic hidden attractor is found in the newly proposed Lorenz-like chaotic system. Some variables of the equilibria-free system can be controlled in amplitude and offset by an independent knob. A circuit experiment based on Multisim is consistent with the theoretic analysis and numerical simulation.
