In this paper, we present a reduced-order memoryless state observer for networked control system with long delays in the control vectors. Then we use z-transform to deal with the long delays. By computing the residual between the output of the practical system and the output of the observer, we detect the fault of the networked system. An illustrative example shows the effectiveness of the approach. Copyright © 2006 IFAC.
