Electromagnetic forces for a new vibration control system: experimental verification

In our previous work we proposed a new concept of the control system in which vibrations of a partially magnetized thin beam are actively suppressed using electromagnetic forces induced by an electric current conducted through the beam. In this experimental study we will demonstrate the effectiveness of the electromagnetic force which plays a major role in our new vibration control system. As a partially magnetized beam is not available at the present moment, a magnetic field generated by a permanent magnet is used to control the motion of a thin elastic beam on which an electric current is conducted through an electric wire glued onto the beam's surface across its breadth. The objective of the present study is to examine if an actually induced electromagnetic force acting on the electric wire is effective in suppressing the beam's vibrations. A feedforward control analysis of the corresponding experiment is performed to confirm experimental results.
