The spatial information given by the distributed sensors (e.g., piezoelectric laminates) can be used to forecast structural damage on localised critical spot. It is well known that a localised structural damage with relative small amplitude does not affect significantly the modal response of the structure, at least at low frequencies. Nevertheless, a local(More)
The aim of this work is to investigate the problem of piezoelectric laminate placement. This problem is addressed in the case of modal identification and active control of plate like structures using piezoelectric laminates. The placement technique is based on the inspection of the controllability Grammian of the system expressed in a modal state-space(More)
