Abstract
Recently, active mass damper systems are being widely used as vibration suppression devices for various structures and industrial equipments. One such application is in the suppression of floor vibration in an office building. The goal of this research is to develop a movable active mass damper system that can suppress these types of floor vibrations. Since this system has to be adjusted for various types of floors, both system identification and controller design processes have to be done each time the system is installed. However these processes generally require more than a certain amount of knowledge and experience. Only experts can install the sytem. This paper mainly focuses on the automatic plant identification and controller design of the proposed active mass damper system in order to eliminate the need for a person to perform this tuning. The controller is designed by using the CTFM based model matching method, and a least square system identification method is used for both plant identification and controller parameter adjustment. The effectiveness of the proposed technique is verified by experiments.
