This work discussed the design of a sliding mode observer for the estimation of actuator
faults in a Takagi–Sugeno fuzzy system with digital communication channel. Signals must …

This article addresses the state and fault estimation problems for a class of quantized Takagi–
Sugeno (TS) fuzzy systems with sensor and actuator faults. Two types of observer design …

This paper proposes a novel fault detection method for Takagi–Sugeno fuzzy systems via
multiple observer design and ellipsoidal analysis. By considering only one fault distribution …

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 …

This paper presents an actuator fault and disturbance estimation scheme using sliding mode
observer (SMO) based on Takagi–Sugeno (TS) fuzzy system model. The TS model is first …

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 …

This paper presents a novel method to address a Proportional Integral observer design for
the actuator and sensor faults estimation based on Takagi–Sugeno fuzzy model with …

This paper addresses the problem of observer-based fault reconstruction for Takagi–
Sugeno fuzzy systems. Two types of fuzzy learning observers are constructed to achieve …

This paper considers zonotopic fault detection observer design in the finite-frequency
domain for discrete-time Takagi–Sugeno fuzzy systems with unknown but bounded …

In this article, optimal observer-based fault detection (FD) and estimation schemes for
Takagi–Sugeno fuzzy systems with process faults are investigated. In particular, an optimal …
