Hidden attractors in electromechanical systems with and without equilibria

摘要

This paper studies hidden oscillations appearing in electromechanical systems withand without equilibria. Three different systems with such effects are considered: translationaloscillator-rotational actuator, drilling system actuated by a DC-motor and drilling systemactuated by induction motor. We demonstrate that three systems experience hidden oscillationsin sense of mathematical definition. While some of these hidden oscillations can be easily seenin natural physical experiments, the localization of others requires special efforts.
