Abstract

Journal of Vibration and Control, Ahead of Print.
The Kalman filter has been widely used in structural dynamic load identification. However, traditional methods based on the augmented Kalman filter are unable to fully utilize measurement data and perform poorly when measurement capabilities are limited, ...
