Magnetorheological damper control in an energy-harvesting vibration reduction system

Abstract

The paper presents results computer simulations conducted for a semi-active vibration reduction system in an object with one degree of freedom. The system consists of a linear magnetorheological (MR) damper connected with an electromechanical transducer (EM) and a spring. This system is an alternative to a typical semi-active MR damper-based vibration reduction system supplied by an external power source. The task of the EM transducer is to harvest a certain part of energy coming from mechanical vibration and convert it into electrical energy. The voltage induced by EM is used to control the MR damper. The performance of the vibration reduction system was tested with various control algorithms applied to the MR damper working.
