This paper studies the integrated design of fuzzy observer-based fault detection (FD) for
nonlinear systems in the presence of external disturbances. To this end, we first approximate …

This paper concerns with the problem of designing fault detection (FD) observer for Takagi-
Sugeno (TS) fuzzy systems subject to local nonlinear models. Different from the quadratic …

This article is concerned with the optimal fault detection issues for discrete-time nonlinear
systems with the aid of Takagi–Sugeno fuzzy dynamic modeling technique. To this end, in …

This paper deals with a real-time-weighted observer-based fault-detection (FD) scheme for
Takagi-Sugeno (TS) fuzzy systems. The essential idea is to develop a weighted diagnostic …

Appearing faults in a practical system is dispensable, and if it is not compensated, it results
in poor system performance or even dysfunction of the system. The fault detection has …

The observer design problem for fault detection is considered for nonlinear continuous–
discrete systems with Takagi–Sugeno fuzzy scheme and finite frequency specification in this …

This article focuses on the design problem of fault detection (FD) observer for a class of
continuous-time nonlinear systems. The index is employed to measure the worst cast fault …

This paper is concerned with a real-time observer-based fault detection (FD) approach for a
general type of nonlinear systems in the presence of external disturbances. To this end, in …

This paper investigates the problem of fuzzy unknown input observer (FUIO)-based fault
estimation for discrete-time Takagi–Sugeno fuzzy systems. Firstly, an augmented system …

In this article, we pay our attention on exploring observer-based actuator fault and sensor
fault reconstruction associated with fault-tolerant control (FTC) for nonlinear systems, which …
