Abstract. This paper deals with a Luenberger Observer structure which is devoted to the identification of state variables of a Linear Time Invariant (LTI) system. In particular, a disturbance acting as an unknown input is estimated under the hypothesis of quasi-stationarity. Without loosing the generality, a system of the second order is taken into consideration and a constructive proposition is proven.
