Contrairement aux filtres de Kalman et aux observateurs asymptotiques, les reconstructeurs d'état ne nécessitent pas l'intégration d'équations différentielles. Ils éliminent les perturbations structurées et sont robustes pour des bruits aux propriétés statistiques mal connues. Les techniques sont, avant tout, d'ordre algébrique. Pour citer cet article : M. Fliess, H. Sira-Ramírez, C. R. Acad. Sci. Paris, Ser. I 338 (2004).


In contrast to Kalman filters and asymptotic observers, the state reconstructors do not need the integration of differential equations. They eliminate structured perturbations and are robust with respect to noises without any precise knowledge of their statistical properties. The techniques used are, primarily, of algebraic nature.
