This paper studies hidden oscillations appearing in electromechanical systems with and
without equilibria. Three different systems with such effects are considered: translational …

A modification of the Hénon method is proposed for the straightforward and simultaneous
computation of time series with “exact” stick-slip transitions and fixed step time series related …

This work is devoted to the investigation of oscillations in a drilling system using an induction
motor with wound rotor as a drive. It is motivated by the problems of drilling rig failures in the …

The following chapter deals with systems of differential equations with discontinuous right-
hand sides. The key question is how to define the solutions of such systems. The most …

We introduce a new analytical method, which allows to find chaotic regimes in non-smooth
dynamical systems. A simple mechanical system consisting of a mass and a dry friction …

This work is devoted to study of electromechanical models of the drilling systems actuated
by an induction motor. This subject is up-to-date due to the fact that failures of the drilling …
