Abstract
In this article, a study of Finite Memory Observers on an unknown input system is treated using augmented states. In this study, noised system is processed and especially state noise due to themodelling of the system with unknown input. After giving a mathematical overview on unknown input observers and after writing Finite Memory Observers principles, results are given according to fault indicators and especially in fault indicator tables.
