A direct approach for full-field state-parameter estimation from fusion of noncollocated multi-rate sensor data using UKF-based algorithms
Dhiraj Ghosh, Adrita Kundu, Suparno Mukhopadhyay
Heterogeneous sensor setups may entail measurements recorded at varying sampling frequencies, commonly known as multi-rate data. For system identification and state estimation with…

Insensitivity-induced potential non-uniqueness in system identification of Bouc-Wen models
Adrita Kundu, Suparno Mukhopadhyay
During system identification of a structural system with Bouc-Wen (BW) restoring force mechanisms, the estimated BW parameters may be different for different sets of input-output m…

Signal-based online acceleration and strain data fusion using B-splines and Kalman filter for full-field dynamic displacement estimation
Aniruddha Das, Ashish Pal, Satish Nagarajaiah +2
Displacement plays a crucial role in structural health monitoring (SHM) and damage detection of structural systems subjected to dynamic loads. However, due to the inconvenience ass…
