Modal filtering for active vibration control of high-rise structures using PVDF sensors

Abstract

This study presents a modal filtering approach to separate the structural modes of a high-rise structure using shaped film sensors. A building like model structure is constructed to realize the proposed model filtering approach. Since it is difficult to define a modal shape function for discrete parameter structures, analytical and experimental approaches are discussed to determine the shape of the sensor. In experiment, the first structural mode of the high-rise structure is successfully filtered and robustness of the sensor output against parameter uncertainty is also tested.
