Physica Scripta, Год журнала: 2024, Номер 99(5), С. 055251 - 055251

Опубликована: Апрель 5, 2024

Abstract A novel 4D fractional-order chaotic entanglement system based on sinusoidal functions is established in this paper. We aim to reveal the relationship between dynamical behavior of new and its coefficients. It found that equilibrium point varies regularly with successive change coefficient. The supercritical pitchfork bifurcation phenomenon discussed stability theory. Furthermore, sufficient conditions threshold for Hopf caused by coefficient are provided. Finally, route chaos explored utilizing multiple numerical indicators, such as spectral entropy complexity, diagrams, Lyapunov exponential spectrum, phase portraits, 0–1 test curves. results indicate addition various attractors, there phenomena period-doubling bifurcations, period windows, coexisting symmetric attractors (periodic or chaotic).

Mathematical Biosciences & Engineering, Год журнала: 2023, Номер 20(11), С. 20093 - 20115

Опубликована: Янв. 1, 2023

In this paper, a fractional-order two delays neural network with ring-hub structure is investigated. Firstly, the stability and existence of Hopf bifurcation proposed system are obtained by taking sum as parameter. Furthermore, parameters delay feedback controller introduced to control successfully bifurcation. The novelty paper that characteristic equation corresponding has time depend on one them. Selecting simultaneously, switching curves in $ (\tau_{1}, \tau_{2}) plane crossing direction obtained. Sufficient criteria for controlled given. Ultimately, numerical simulation shows can effectively system.
