Abstract :
In this paper, a constant gain unknown input observer (U.I.O) for bilinear systems is proposed. The design procedure is based on the solution of an LMI which ensure the observer stability using Lyapunov approach. The norm of the estimation error decays to zero asymptotically. Sufficient existence conditions for the U.I.O are given. The efficiency of the new observer design method is applied to a semi-active suspension vehicle.
