Journal ArticleDOI
Global synchronization of two parametrically excited systems using active control
TL;DR: In this article, the authors apply an active control technique to synchronize a kind of two parametrically excited chaotic systems based on Lyapunov stability theory and Routh-Hurwitz criteria.
Journal ArticleDOI
Inducing or suppressing chaos in a double-well Duffing oscillator by time delay feedback
TL;DR: In this paper, the chaotic behavior of a double-well Duffing oscillator with both delayed displacement and velocity feedbacks under a harmonic excitation is investigated by means of the Melnikov technique, and the necessary condition for the onset of chaos resulting from homoclinic bifurcation is derived analytically.
Journal ArticleDOI
Stochastic bifurcation in duffing system subject to harmonic excitation and in presence of random noise
TL;DR: In this article, a global analysis of stochastic bifurcation in a special kind of Duffing system, named as Ueda system, subject to a harmonic excitation and in presence of random noise disturbance is studied in detail by the generalized cell mapping method using digraph.
Journal ArticleDOI
Chaos control by harmonic excitation with proper random phase
TL;DR: In this paper, the authors show that the random phase plays a decisive role for chaos control in nonlinear dynamic systems, whether a suppressing one or a generating one, by adjusting the level of random phase and determined by the sign of the top Lyapunov exponent of the system response.
Journal ArticleDOI
Principal response of duffing oscillator to combined deterministic and narrow-band random parametric excitation
TL;DR: In this article, the principal resonance of a Duffing oscillator to combined deterministic and narrow-band random parametric excitations is investigated, and the effects of damping, detuning, and magnitudes of deterministic, narrowband and random excitations are analyzed.
