Dynamics of an Energy Harvester With Hysteresis Friction

Abstract

A model of an energy harvester converter with hysteresis viscous friction is considered. The mechanical part of the energy harvester is made in the form of an inverted pendulum. The hysteresis is formalized within the framework of the Preisach model, which is a continuum analogue of a system of non-ideal relays connected in parallel. Within the framework of numerical experiments, the dependences of the dynamic parameters, in particular, the angle of deflection of the pendulum and the voltage on the load, as well as phase portraits, on the value of the coefficient characterizing the effect of hysteresis friction, were investigated. The role of nonlinear effects is demonstrated.
