%X This paper is concerned with the robust fault detection (FD) problem for linear discrete time-delay systems in finite frequency domain. By fault estimate techniques, the FD detection filter design problem is formulated as a delaydependent H-infinity filter design problem. This paper directly gives linear matrix inequality conditions for finite frequency FD performance, and avoids the approximations associated with frequency weights. Finally, an example is given to show that the proposed delay-dependent FD filter can achieve better FD performance than other existing algorithms.
