EXPERIMENTAL STUDY ON ACTIVE VARIABLE DAMPING SYSTEM BY SHAKING TABLE
|
´˜^i‰pjF
A shaking table experiment was performed on a three-story model structure installed with the Active Variable Damping System. The system was equipped with the variable hydraulic damper which consumed only a small amount of electric power to control the damping force. In the experiment, the velocity feedback control which is based on the state-regulator-theory was employed. The variable hydraulic damper, newly developped velocity sensors and control computer with DSP performed as expected and the response of the model structure could be significantly reduced. Furthr, the appropriateness of the proposed analytical was comfirmed by the results of numerical simulation.
