Generic bifurcation of sliding vector fields

WebAbstract In this paper, we analytically consider sliding bifurcations of periodic orbits in the dry-friction oscillator. The system depends on two parameters: F, which corresponds to …

Codimension two singularities of sliding vector fields

WebWe are interested in finding under what conditions the family has a crossing limit cycle, when the sliding region changes its stability. We call this phenomenon the pseudo-Hopf bifurcation. This class of systems is motivated by piecewise-linear control systems which have not yet been treated in the context of crossing limit cycles. WebAbstract. Using the singularity theory of scalar functions, we derive a classification of sliding bifurcations in piecewise-smooth flows. These are global bifurcations which occur when … cr bss tmx 410 mh8–108a black frame https://bjliveproduction.com

Generic bifurcation of certain piecewise smooth vector fields

WebFeb 1, 2024 · In particular, it has been shown that, in this scenario, the sliding vector field undergoes a saddle–node bifurcation. However, the unfolding dynamics in the crossing regions has not been addressed. We aim to fill this gap, and thus to present complete and detailed results on the unfolding dynamics of a Fold bifurcation of T-singularities. WebOct 18, 2024 · The purpose of this work is to study the generic singularities of planar piecewise vector fields Z which discontinuity set is given by the zeros of the map f (x_1,x_2). As it is known that there are coordinates around the origin such that f can be written as f (x_1,x_2)=x_1^2 \pm x_2^2.

WebThe Teixeira singularity can undergo an interesting bifurcation, namely when a pseudo-equilibrium point crosses the two-fold singularity, passing from the attractive sliding region to the repulsive sliding region (or vice versa) and, … WebMay 15, 2024 · Such a bifurcation occurs in the sliding vector field and creates, in this field, an unstable limit cycle. The limit cycle is connected to the switching manifold and disappears when it touches the visible–invisible two-fold point, resulting in a homoclinic loop which itself closes in this two-fold point.
