Control Method Based on Energy Absorption Rate of Semi-Active Controlled Tuned Mass Damper Adaptable to a Structure's Period Fluctuation

This paper proposes a control method for a semi-active controlled tuned mass damper (TMD) adaptable to the period fluctuation of the target structure. It is based on the idea of maximizing the TMD's absorbing energy. First, previous control methods are reviewed from the aspects of performance and applicability. Next, the concept and algorithm of the proposed control method are described, and the relationship between its response control performance and absorbing energy is investigated. Finally, earthquake response analyses are performed that compare the proposed control method with other types of TMD.
