Abstract

Self-sensing active vibration damping is advantageous if external sensors cannot be collocated with the actuators or these sensors add too much weight or cost. When self-sensing, electrodynamic actuators are used damping is directly added to an attached structure without the need of potentially destabilizing electronic integrators or differentiators. In this paper self-sensing control with a shunted resistor, positive current feedback and induced voltage feedback are investigated in simulations and experiments. Experiments with a commercial shaker on a clamped plate show that its vibration attenuation is increased from 5 to 15dB and the control bandwidth is more than doubled when the appropriate control scheme is used. © 2006 IOP Publishing Ltd.
