In this article, we consider a type of multi-input-multi-output networked control systems (NCSs) in whichthe network-induced time delays for different inputs are different. For those unstable and/or poorly dampedeigenvalues, we propose a reduced-order memoryless state observer design approach. The full-order statevector of the original systems using the reduced-order observer is reconstructed. We prove that the 
-stabilityof the state error dynamics can be guaranteed. Meanwhile, by computing the residual between the output ofthe practical systems and the output of the reduced-order observer, the fault-detection scheme of the NCSsis given. An illustrative example shows the effectiveness of the proposed method.
