Abstract

In this paper we study singularly perturbed systems with discontinuity surfaces. This means that we have a system of ordinary differential equations with a small parameter and a piecewise smooth vector field. The state where the trajectory moves on the discontinuity surface is called sliding mode. We present an asymptotic representation for trajectories with temporary sliding and apply the result to stick-slip vibrations.
