Study for the bifurcation topological structure and the global complicated character of a kind of nonlinear finance system (I)
TL;DR: In this article, a mathematical model of a kind of complicated financial system, and all possible things that the model shows in the operation of our country's macro-financial system are analyzed.
Journal ArticleDOI
Response of parametrically excited duffing-van der pol oscillator with delayed feedback
TL;DR: In this paper, the authors derived slow-flow equations on the amplitude and phase of response of a parametrically excited Duffing-van der Pol oscillator under linear-plus-nonlinear state feedback control with a time delay.
Journal ArticleDOI
The matric algorithm of lyapunov exponent for the experimental data obtained in dynamic analysis
TL;DR: The calculating results validate that the matric algorithm has sufficient accuracy, and the relationship between the character of attractor and the value of Lyapunov exponent is studied.
Journal ArticleDOI
Bifurcation in a parametrically excited two-degree-of-freedom nonlinear oscillating system with 1:2 internal resonance
季进臣,陈予恕,Ji Jinchen,Chen Yushu +3 more
TL;DR: In this article, the nonlinear response of a two-degree-of-freedom nonlinear oscillating system to parametric excitation is examined for the case of 1∶2 internal resonance and, principal parametric resonance with respect to the lower mode.
Journal ArticleDOI
Study on prediction methods for dynamic systems of nonlinear chaotic time series
TL;DR: High accurate identification can be guaranteed by applying wavelet networks to identify parameters of self-related chaotic models and more valid prediction of the chaotic time series including noise can be achieved accordingly.
