Saddle node bifurcation in a PLL

Proceedings of Southeastcon '93, 2002
New results are given on the phenomenon of false lock in second-order, Type I PLLs (phase-locked loops) with a constant frequency reference of /spl omega//sub i/ and a VCO (voltage-controlled oscillator) quiescent frequency of /spl omega//sub o/. Of interest here is the stable false lock state whose frequency error approaches /spl omega//sub i/-/spl ...

NONAUTONOMOUS SADDLE-NODE BIFURCATION IN A CANONICAL ELECTROSTATIC MEMS

International Journal of Bifurcation and Chaos, 2013
We study the existence and stability of periodic solutions of a canonical mass-spring model of electrostatically actuated Micro-Electro-Mechanical System (MEMS) by means of classical topological techniques like a priori bounds, Leray–Schauder degree and topological index. A saddle-node bifurcation is revealed, in analogy with the autonomous case.

BASIN ORGANIZATION PRIOR TO A TANGLED SADDLE-NODE BIFURCATION

International Journal of Bifurcation and Chaos, 1991
Heteroclinic and homoclinic connections of saddle cycles play an important role in basin organization. In this study, we outline how these events can lead to an indeterminate jump to resonance from a saddle-node bifurcation. Here, due to the fractal structure of the basins in the vicinity of the saddle-node, we cannot predict to which available ...

Numerical Computation of Saddle-Node Homoclinic Bifurcation Points

SIAM Journal on Numerical Analysis, 1993
This paper presents the convergence and stability of a numerical method for computing the intersection points of homoclinic bifurcation curves and saddle-node or transcritical bifurcation curves.

Saddle-node bifurcations in the spectrum of HOCl

The Journal of Chemical Physics, 2000
A detailed analysis of the bound-state spectrum of HOCl (hypoclorous acid) in the ground electronic state is presented. Exact quantum mechanical calculations (filter diagonalization) are performed employing an ab initio potential energy surface, which has been constructed using the multireference configuration-interaction method and a quintuple-zeta ...

Discontinuous immittance due to a saddle node bifurcation

Journal of Electroanalytical Chemistry, 1998
The Frumkin isotherm for the electrosorption reaction is S-shaped for the interaction parameter values lower than a critical level, leading to a hysteresis loop during steady-state studies. It is shown that isotherm branch switching phenomena can occur during the study of the electrosorption reaction by electrochemical impedance spectroscopy.

Saddle–Node Bifurcation Leading to Survival Mosquitoes

International Journal of Bifurcation and Chaos
A saddle–node bifurcation is demonstrated in a model of mosquito population growth. This bifurcation helps us understand the dynamics of two stages in the model: the aquatic stage (which includes the egg, larva, and pupa) and the nonaquatic stage (the mature mosquito).

The saddle-node Hopf bifurcation with global reinjection [PDF]

, 2003
A simultaneous saddle-node and Hopf bifurcation is a basic codimension-two local bifurcation of vector fields with a phase space of dimension at least three. Its local unfoldings are now well-known and it has been found as an organizing center of the dynamics in many vector fields arising in applications.
