Identifying modal coordinates from output-only data is a key link of virtual sensing
technology based on the modal extension method. It is also one of the goals of optimal …

Identifying the local properties of a structure, either to perform structural health monitoring or
to fine tune a numerical model, requires the updating of a large number of parameters. With …

Virtual sensing enables estimation of stress in unmeasured locations of a system using a
system model, physical sensors and a process model. The system model holds the …

Online monitoring and health assessment of rotating bladed disks have always been a hot
topic in the engineering field. However, the existing monitoring methods cannot fully …

The fusion estimation issue of sensor networks is investigated for nonlinear time-varying
systems with energy constraints, time delays as well as packet loss. For the addressed …

The strain history affecting the fatigue life of fixed offshore support structures is one of the
most important topics in structural monitoring. However, some critical fatigue locations are …

This paper describes an estimator incorporating the Unscented Kalman Filter (UKF)
technique and multibody system dynamics, to determine the state of the flexible multibody …

State feedback is mostly used in the active vibration control of structural systems. However,
the most challenging problem is to achieve the whole state of the structure. Another issue in …

This paper presents a Bayesian-based approach to realize virtual strain sensing and
quantify the uncertainty in these estimates using sparse output-only measurements. This …

Structural health monitoring of bridges aims to provide an assessment of the condition of the
structure, using collected structural response. The efficacy of the methods usually is …
