System identification with piezoceramic actuators

At LMSSC, Cnam, Paris, October 2nd 2008
Konrad Schuster (Institute for Structural Analysis, Technische Universität Braunschweig, Germany)

In the presentation an online structural health monitoring concept is introduced, which enables the system identification and the damage detection of mechanical structures. Piezoceramic actuators are used to excite the structure and to measure the dynamic system response. For the damage detection two damage indicators are introduced, based on a model updating algorithm.
