A STUDY ON SEMI-ACTIVE CONTROL USING MAXWELL-MODEL VARIABLE DAMPER

摘要

In recent years, semi-active control has been studied more often in vibration control fields. Semi-active system belongs to a nonlinear system and controller design is not easy. Therefore, the definitive control rule is still not established. This study proposes easy control rule which has only changing the damping coefficient of the seismic isolation system to the maximum and the minimum using the Maxwell-model variable damper and clarifies the influence in numerical analysis which design parameter affect the system, further compares the effect with the case of passive system.
