Active control of beam vibration using non-model based algorithm

Abstract

Active vibration control using non-model based algorithm was developed for beam vibration suppression by the electromagnetic force. The algorithm detects the vibration frequencies in real-time using the laser displacement sensor signal, and then activates the electromagnets for vibration control. The control algorithm does not use any mathematical modeling of the structure. The experimental results show that the proposed method can be applied for the vibration control of beams with variable dynamic characteristics and excitation frequencies. © The Society for Experimental Mechanics, Inc. 2012.
