A PZT-based technique for SHM using the coherence function
(2011-06-13)
This paper presents a new approach for damage detection in structural health monitoring systems exploiting the coherence function between the signals from PZT (Lead Zirconate Titanate) transducers bonded to a host structure. ...
New Improved Version of J 1 ...J 4 Interferometry Method and its Application to Nanometric Vibration Measurements
(New York, 2014-03-17)
Piezoelectric ceramics, such as PZT, can generate
subnanometric displacements, bu
t in order to generate multi-
micrometric displacements, they should be either driven by high
electric voltages (hundreds of volts
), ...

False alarms in damage detection approaches
(2008-12-01)
Structural Health Monitoring (SHM) denotes a system with the ability to detect and interpret adverse changes in structures in order to improve reliability and reduce life-cycle costs. The greatest challenge for designing ...
Structural Health Monitoring based on AR models and PZT sensors
(2012-12-01)
This paper presents a new approach for damage detection in Structural Health Monitoring (SHM) systems, which is based on the Electromechanical Impedance (EMI) principle and Autoregressive (AR) models. Typical applications ...
System Identification and active modal control of a flexible truss structure
(2015-01-01)
The aim of this paper is to illustrate the active control of vibration of a flexible truss structure using a model-based digital controller. The state-space model of the system is derived using a system identification ...
