Tuned Mass Damper를 이용한 Linear Quadratic Gaussian 하이브리드 제진 = Linear Quadratic Gaussian Hybrid Control for a Structure Subjected to Seismic Excitation.

다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate the effectiveness of a LQG Hybrid controller to suppress the earthquake disturbance for the building structure. The ground acceleration of N-S component of El-Centro earthquake is scaled to confirm that the building behaves within the elastic range. The tuned mass damper(TMD) on the top floor regulated by LQG algorithm is designed to control the floor displacements. The displacement responses of the hybrid control are compared with those obtained from an active control along with a passive control. The results showed that the LQG hybrid control used approximately 50% less input forces than an active control to satisfy the performance criteria.
