A Vibration Control of Multi-layer Structure by LQ Type $H_{\infty}$ Control Theory

LQ 형 $H_{\infty}$ 제어기법에 의한 다층 구조물의 진동제어

This paper presents the vibration control for the two degree-of-freedom which is a reduced model of multi-layer structure. This reduced model is designed for the first and second order resonance in the low frequency domain where the disturbance such as the earth quake has the large energy. And a designed controller using the LQ type $H_{\infty}$ control theory shows the good performance for the impulse disturbance through the experimental results and the simulation results respectively.
