Instead of traditional Tikhonov regularization, sparse regularization methods like ℓ 1
regularization have been a popular choice for impact force identification because it can …

As a typical inverse problem, impact force identification tends to be a challenge owing to its
ill-posedness. Recently, the sparse characteristic of the impact force in time domain are …

The inherent sparse structure of impact forces has garnered considerable attention in the
field of impact force identification. However, conventional convex sparse regularization …

In practice, simultaneous impact localization and time history reconstruction can hardly be
achieved, due to the ill-posed and under-determined problems induced by the constrained …

The standard sparse regularization method based on l 1-norm minimization for impact force
identification has already proved to be an interesting alternative to the classical …

Many convex regularization methods, such as the classical Tikhonov regularization based
on l 2-norm penalty and the standard sparse regularization method based on l 1-norm …

Impact force identification plays an important role in structural health monitoring, dynamics
optimization design, milling force measurement, etc. However, the traditional L2 norm-based …

We recently proposed a non-convex sparse regularization method in the ADMM framework
to reconstruct and localize unknown impact forces. This method surpasses the convex ℓ 1 …
