The design of observers for linear systems with unknown, time-varying, bounded delays (on
the state and on the input) still constitutes an open problem. In this paper, we show how to …

A common requirement implicit in the current methods for the design of robust state
estimators and robust fault detection filters is that the first Markov matrix must be non-zero …

Many observer‐based fault diagnosis strategies proposed for linear systems, subject to
unknown inputs, operate based on three assumptions. The first assumption is that the …

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 …

Abstract Sliding Mode Observer (SMO) based methods have been extensively used for Fault
Estimation (FE). However, the fault detection (FD) problem for these SMO based FE methods …

In order to improve the safety and reliability of the hypersonic flight vehicle, a sliding mode
observer-based fault detection scheme is applied in this paper to handle the actuator fault …

This paper presents new results in observer-based robust fault reconstruction for uncertain
systems using cascaded sliding mode observers. Signals from an observer are used as the …

This paper presents a disturbance decoupled fault reconstruction (DDFR) scheme using
cascaded sliding mode observers (SMOs). The processed signals from a SMO are found to …

The actuator failure in a Marine Vehicle (MV) possibly happens because of the complicated
marine environment. This paper proposes an Adaptive Generalized Actuator Fault …

This paper presents a sensor fault tolerant control approach for grid connected microgrids.
The proposed approach diagnoses (detects and estimates) faults in the sensed microgrid …
