Abstract

In this paper, a simple non-model based control strategy is developed to control stay cable vibration using MR dampers. The strategy is an integral plus double integral control based on the collocated accelerometer feedback. To experimentally study this control method, a model stay cable equipped with an Magneto-Rheological(MR) damper is used in this study. To demonstrate the effectiveness of the proposed controller, comparisons of the unimpeded stay cable, passive off, passive on and the proposed integral plus double integral control are conducted. For each case, the damping ratio of the stay cable vibration is calculated. Comparisons of the experimental results show that non-model based vibration control of the stay cable using the MR damper is most effective in reducing the stay cable vibration.
