Abstract |
This paper proposes an effective vibration control algorithm using a smart damping system for vibration mitigation. The proposed algorithm, which extends Lyapunov stability theory into a unified system, enables to correct the errors in quantization by its increased stability. The validity of this control method is proved in the experiment on a control model of two-storied building structure. Smart damper is used for shear mode MR damper in the experiment, and its control effectiveness is evaluated. In this vibration control experiment, control effect under the influence of earthquake event is evaluated to various performance index, and thus the algorithm presented here is proved to be valid. |
