Design and Control of Semi-Active Tuned Mass Damper
- 발행 : 2014.10.29
초록
This paper is concerned with design and control of semi-active tuned mass damper. The equipment consists of permanent magnet and coil. If current flowing in coil is changed, the natural frequency of the semi-active tuned mass damper is changed. In previous research, a current flowing in coil was changed manually. In this time, we design the feedback control system. The experiment proceed that the excitation frequency is shifted from 4Hz to 9Hz. The result of experiment proves that semi-active tuned mass damper is better than passive tuned mass damper in performance of absorbing vibration.
