Abstract: Abstract:  Problems related to fault detection of
networked control systems (NCSs) with both uncertain time-varying
delay and quantization error are studied in this paper. A novel
model with the form of polytopic uncertainty is given to represent
the influences of both the time-varying delay and the quantization
error, and then the reference model based method is used to design
the residual generator that is robust to both unknown
network-induced delay and unknown inputs. A numerical example is
also given to illustrate the merits of the presented method. The
proposed method can be regarded as an extension of the
authors' former work, which can only deal with time-varying delay.

Key words:
