Abstract :
This paper is a contribution to the problem of systems prognosis. More precisely, in this work, the goal is to introduce an unknown input interval observer for a class of uncertain system with an unknown input for systems prognosis. The observer synthesis is applied to unknown variables estimation of an electromechanical oscillator with a non-stationary two-well potential to illustrate the pertinence of the proposed approach.
