Abstract

The objective of this article is the detection of tip-fractures as faults in the normal operation of an Atomic Force Microscope (AFM), where the system's characteristics (damping, tip-radius) vary. The system is modeled as a vibrating cantilever beam whose deflection can be measured. The measurements are assumed to be corrupted by noise within a priori known magnitude. The certainty sets within which the nominal time-varying parameters of the AFM reside are computed via a variation of an ellipsoidal Set Membership Identification technique. The fault is captured at the time instant of the existence of an outlier-measurement.
