摘要：This paper deals with the fault detection flter design problem for linear time invariant time-delay systems with unknown input. The core of our study is to a) take the behavior of delayed state and measurement into consideration when the observer-based fault detection fter is constructed; b) solve the formulated fault detection fter design problem by combining of using the left eigenstructure assignment approach and H∞ optimization technique. Through a suitable choice of the fter gain matrices and residual weighting matrix, the residual can be completely decoupled from the delay-free unknown input, while the inflence of the delayed unknown input on residual is minimized in the sense of H∞ norm. Numerical simulation is used to illustrate the efficiency of the proposed method. © 2004 IEEE.
