Discrete flatness for non linear systems FDI
Résumé
This Fault detection is essential for the survivability of many systems. Since many systems present highly nonlinear dynamics, the applicability of general fault detection techniques designed mainly for linear systems is very questionable. The purpose of this communication is to investigate the usefulness of the differential flatness theory of a non linear system such as a four rotor aircraft to design an efficient fault detection scheme. In this communication, after introducing the concept of difference flat nonlinear systems, a fault detection scheme based on difference flatness.
