VIBRATION CONTROL OF A LARGE-SCALE TEST BUILDING USING HYBRID MASS DAMPER SYSTEM APPLIED ROBUST CONTROL THEORY

摘要

The authors since 1990 have been working on the study and development of a vibration control system designed through use of Linear Quadratic optimal control theory (LQR). However, the LQR system needs many sensors, integrating amplifier, and cable to achieve vibration. To address these and other issues, as is well-known, robust control theory utilizes an efficient technique for vibration control of tall buildings. H∞control theory andμ-synthesis, which are representative of robust control theory and are which reduce the vibration of a building using only the absolute acceleration of the roof floor, have robust stability and robust performance. This paper describes design of a control system based on H∞control theory andμ -synthesis, as applied in an Active Mass Damper (AMD) system installed on a building. It has been demonstrated by simulations and observations that the designed controller has sufficient vibration AMD performance and robust performance under excitations.
