Abstract :
Unknown input observers take the knowledge of perturbations influence into account. If detectability and minimum phase conditions are assumed, states estimation can be decoupled from perturbations. This work shows that unknown input observers can be built for systems which perturbations have an identical immediate effect, or with delay greater than one.
