Modelling and control of active damping for vibration suppression

A modelling approach has been developed to describe the flexural vibration behaviour of a cantilevered beam when excited using piezoceramic patches bonded to a constraining layer. Predictions of dynamic behaviour, obtained using the models are validated by comparison with results from laboratory experiments. The models are then used in control system design studies to demonstrate the improvements in stability and performance achieved using this method over that achieved using conventional active control.
