Iterative controller tuning for processes with fold bifurcations
Computer Aided Chemical Engineering, 2007Abstract Processes involving fold bifurcation are notoriously difficult to control in the vicinity of the fold where most often optimal productivity is achieved . In cases with limited process insight a model based control synthesis is not possible.

Odd-Number Orbits Close to a Fold Bifurcation
, 2011The previous section showed that the alleged odd-number theorem is not valid for autonomous systems and that in fact an odd-number orbit born in a subcritical Hopf bifurcation can be stabilized by time-delayed feedback control. Although this is a very generic example, the question arises whether this situation close to the Hopf bifurcation is special ...

Examples of fold bifurcation in a one-dimensional systems [PDF]
, 2017 In this paper will be analyzed a fold bifurcation (or saddle-node bifurcation) in one-dimensional systems, which depend of one parameter r. The analysis will be made via two examples. The examples will analyze the graphical presentations and bifurcation diagram.

Discontinuous Fold Bifurcations
Systems Analysis Modelling Simulation, 2003This article treats discontinuous fold bifurcations of periodic solutions of discontinuous system. It is shown how jumps in the fundamental solution matrix lead to jumps of the Floquet multipliers of periodic solutions. A Floquet multiplier of a discontinuous system can jump through the unit circle causing a discontinuous bifurcation.

Fold Bifurcations in Discontinuous Systems
Volume 7A: 17th Biennial Conference on Mechanical Vibration and Noise, 1999Abstract This paper treats discontinuous fold bifurcations of periodic solutions of discontinuous systems. It is shown how jumps in the fundamental solution matrix lead to jumps of the Floquet multipliers of periodic solutions. A Floquet multiplier of a discontinuous system can jump through the unit circle causing a discontinuous ...

On cyclic fold bifurcations in nonlinear systems
2000 IEEE International Symposium on Circuits and Systems. Emerging Technologies for the 21st Century. Proceedings (IEEE Cat No.00CH36353), 2002Approximations to recover the branch of multiple periodic solutions starting from a Hopf bifurcation under the variation of the main bifurcation parameter are proposed. This task is accomplished with a normal form method and, simultaneously, by using a frequency domain approach.

BIFURCATIONS OF RELAXATION OSCILLATIONS NEAR FOLDED SADDLES
International Journal of Bifurcation and Chaos, 2005Relaxation oscillations are periodic orbits of multiple time scale dynamical systems that contain both slow and fast segments. The slow–fast decomposition of these orbits is defined in the singular limit. Geometric methods in singular perturbation theory classify degeneracies of these decompositions that occur in generic one-parameter families of ...
