Filippov系统局部折叠奇异滑动全局分支的正则化

Regularization of sliding global bifurcations derived from the local fold singularity of Filippov systems

Carles Bonet Revés, Tere M. Seara

摘要:

本文研究了Filippov系统的一般可见折叠奇点的Sotomayor-Teixeira正则化。将几何Fenichel理论推广到折叠之外,用渐近方法确定正则化系统的轨道与Filippov系统的广义解的偏差.这一结果被应用到一些整体滑动分支的正则化,如周期轨道的掠滑或滑鞍同宿,以及一些经典的干摩擦问题。粗略地说,我们看到,局部的,也是全球性的,正则化的分歧保持拓扑特征的滑动。

英文摘要:

In this paper we study the Sotomayor-Teixeira regularization of a general visible fold singularity of a Filippov system. Extending Geometric Fenichel Theory beyond the fold with asymptotic methods, we determine there the deviation of the orbits of the regularized system from the generalized solutions of the Filippov one. This result is applied to the regularization of some global sliding bifurcations as the Grazing-Sliding of periodic orbits or the Sliding Homoclinic to a Saddle, as well as to some classical problems in dry friction. Roughly speaking, we see that locally, and also globally, the regularization of the bifurcations preserve the topological features of the sliding ones.
