Fault detection of networked dynamical systems (NDSs) has attracted ever-increasing
attention since it can maintain high-quality products as well as operational safety …

General recent techniques in fault detection and isolation (FDI) are based on H∞
optimization methods to address the issue of robustness in the presence of disturbances …

This brief studies the problem of fault detection for a class of uncertain state-feedback
tracking control systems with constant reference inputs and bounded disturbances. The …

Aiming at early detection of faults in dynamic systems subject to external periodic
disturbances, this paper proposes a new generalized proportional-integral observer (GPIO) …

This paper studies the integrated fault detection and control problem for linear parameter‐
varying systems. A parameter‐dependent detector/controller is designed to generate two …

This article presents a novel disturbance decoupling generalized proportional–integral
observer (DD-GPIO) for the early detection of sensor faults in dynamic systems subject to …

The problem of simultaneous fault detection and control (SFDC) for linear continuous‐time
switched systems is addressed in this paper. An H∞ formulation of the SFDC problem using …

The paper considers the fault detection problem over finite-frequency domain for a class of
discrete time-delayed networked systems subject to round-robin protocol. This protocol is a …

This paper is concerned with the mixed H2/H∞ control problem for a class of stochastic time-
varying systems with nonlinearities. The nonlinearities are described by statistical means …
