Abstract :
This paper addresses the robust fault detection observer design issue for discrete linear time invariant (LTI) systems with parameter uncertainties in a polytope and subjected to unknown inputs. The observer design is investigated under the H∞/H- index framework in the finite frequency domain where the generalized KYP lemma is utilized. The threshold design is investigated also in the finite frequency range. An example is given to illustrate the results obtained in this paper.
