A Study on Vibration Control of Multi-layer Structure by $H_{\infty}$ Control

$H_{\infty}$ 제어기법에 의한 다층 층상 구조물의 진동제어에 관한 연구

This paper is concerned with the vibration control of multi-layer structure for ultra-tall buildings and main tower of large bridge etc. We have modeled the multi-layer structure with the distributed mass system as the lumped mass system of two-degree-of-freedom structure and made experimental equipment. The H$_{\infty}$ control theory is applied to the design of the control system. The designed control system is simulated by computer. As a result, the designed H$_{\infty}$ controller showed good vibration control performance to impact excitation and the good frequency response.e.
