Identification of Time-Varying External Force Using Group Sparse Regularization and Redundant Dictionary

Identification of Time-Varying External Force Using Group Sparse Regularization and Redundant Dictionary

How to accurately identify unknown time-varying external force from measured structural responses is an important engineering problem, which is critical for assessing the safety condition of the structure. In the context of a few available accelerometers, this paper proposes a novel time-varying ext...
