Abstract :
This paper deals with the development of a timely integrated scheme of actuator fault diagnosis and accommodation. A predefined time diagnosis is elaborated based on a Finite Time Unknown Input Observer (FTUIO). After a finite time, a precise fault estimation is provided by the FTUIO to the accommodation module based on the Pseudo-Inverse Method PIM. A simulation is done on an aeronautic model to illustrate the theoretical development.
