“…There are also several survey papers, of which we mention Isermann and Balle (1997), Isermann (1997) and Gertler (1997). The approaches to design suitable residuals are: parity space design (Chow and Willsky, 1984;Ding et al, 1999;Gertler, 1997), unknown input observer (Hong et al, 1997;Hou and Patton, 1998;Wang and Daley, 1996;Wunnenberg, 1990;Yang and Saif, 1998) and in the frequency domain (Frank and Ding, 199413;Sauter and Hamelin, 1999). A completely different approach is based on reasoning and computer science, and examples here are A r z h (1996), Blanke et al (1997), Larsson (1994) and Larsson (1999).…”

“…On the research of fault diagnosis for linear time-delay systems, Yang and Saif in [34] first proposed a scheme of actuator and sensor fault diagnosis using an unknown input observer and a technique of input estimation for systems with time-delays only in the state. In this work, modeling uncertainties were not considered and some assumptions on the system's structure decomposition were unreasonable.…”

In this paper, the problem of robust synchronization and fault detection for a class of masterslave systems subjected to some nonlinear perturbations and mixed neutral and discrete time-varying delays is investigated based on an H ∞ performance condition. By introducing a descriptor technique, using Lyapunov-Krasovskii functional and a suitable change of variables, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities to synthesize the residual generation scheme. The explicit expression of the synchronization law is derived for the fault such that both asymptotic stability and a prescribed level of disturbance attenuation are satisfied for all admissible nonlinear perturbations. A numerical example with simulation results illustrates the effectiveness of the methodology.

“…Yang and Saif (1998) addressed fault diagnosis for a class of state-delayed dynamic systems, in which the actuator and sensor faults, as well as other effects, such as disturbances and higher-order nonlinearities, were considered as unknown inputs. More recently, Koenig et al (2005) dealt with the design problem of full-order observers for linear continuous delayed state and inputs systems with unknown input and time-varying delays.…”

Networked Control Systems (NCSs) deal with feedback control systems with loops closed via data communication networks. Control over a network has many advantages compared with traditionally controlled systems, such as a lower implementation cost, reduced wiring, simpler installation and maintenance and higher reliability. Nevertheless, the networkinduced delay, packet dropout, asynchronous behavior and other specificities of networks will degrade the performance of closed-loop systems. In this context, it is necessary to develop a new theory for systems that operate in a distributed and asynchronous environment. Research on Fault Detection and Isolation (FDI) for NCSs has received increasing attention in recent years. This paper reviews the state of the art in this topic.
