概要

論文の詳細を見る
This report describes the active control systems for reducing floor impact noise. The control system is comprised of actively controlled modular thin plates, which wholly cover the surface of concrete slab structure in the ceiling, and in each of which the mechanical vibration is controlled independently with electro-magnetic actuators. The final target is to commercialize the proposed active control system, but presently the development is going on. In order to achieve the target, construction of a simplified robust feedback control or an output feedback control is investigated in the following report. To prepare for this investigation, derivation of the dynamic model is pursued basing on analytical modelling.
