Introduction

Fault detection, isolation and diagnostics, for fatigue prevention, aided control and condition-based maintenance.

Early warning of small deviations of a system with respect to a reference behavior considered as normal.

Detection and diagnostics of changes in the parameter vector of parametrized continuous dynamical systems.
