| Abstract: | This paper is concerned with the robust fault detection (FD) problem for linear continuous time-delay systems. Using H_/H-infinity fault detection techniques, we design the fault detection observer and give the design conditions for the delay dependent FD observer. We provide linear matrix inequality conditions for finite frequency FD performance, and avoid the approximations associated with frequency weights. An example is given to show that, in comparison with existing results, the proposed delay-dependent FD observer can achieve better FD performance. |
| Keywords: | fault detection (FD) delay-dependent H_/H-infinity observer linear matrix inequalities (LMIs) |
