Kalman observer approach towards force reconstruction from experimental AFM measurements
Résumé
This paper presents an observer-based approach for weak force measurement via AFM experiments: the idea is to directly reconstruct the force to be measured, from the cantilever de ection actually measured by an optical device and some appropriate observer design. This design classically relies on a dynamic model, which is here beforehand identified. The proposed method is shown to be fairly efficient via experimental illustrative results.
