Modelling and control of a smart beam

Authors


Abstract

In this paper, a linear controller based on the Lyapunov stability theorem is designed and implemented on a smart beam. This smart beam consists of a steel beam with a piezoactuator bonded to it. The controller is used to attentuate the vibrations of the smart beam while exciting it by it's first eigenmode. A super element (SE) model of the same beam is firstly derived, and the controller is implemented on the SE and results are shown. (© 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
