Abstract :
This paper addresses the robust fault detection observer design for discrete LTI systems with additive model uncertainties. The observer design is investigated under the Hinfin/H- index framework in the finite frequency domain where the generalized KYP lemma is used. The threshold design and the worst undetectable fault size estimation are also considered in this paper. A practical application example is given to illustrate the effectiveness of the algorithm obtained in the paper.
