Experimental realization and simulations a self-sustained Macro ElectroMechanical System

This paper deals with experimental realization and simulations of a self-sustained electromechanical system made up of an electrical implementation of a van der Pol-Duffing type oscillator driving a macro scale mass–spring–damper linear oscillator. Using fundamental laws such as Newton and Kirchhoff laws, the parts of the system are characterized and constraints for experimental realization of a prototype are defined. Modelling equations are derived that show the possibility of self-oscillations. Experimental simulations reveal that the proposed device exhibits periodic oscillations and complex dynamics. These results are consistent with published theoretical results.
