In this article, a novel approach for model-based sensor fault detection and estimation of gas
turbine is presented. The proposed method includes driving a state-space model of gas …

Sensors are one of the crucial components in gas turbines and the failure in sensor
measurements can lead to serious problems in maintaining their safety and performance …

An aero-engine is a complex aerodynamic thermal system, which can operate in extreme
environments for long periods. It is crucial to diagnose any faults of the aero-engine control …

In complex systems, observers play a vital role in fault diagnosis and performance
monitoring. Hence, the accuracy of these observers is very important. In this paper, an …

For a sensor fault diagnostic system of aircraft engines, the health performance degradation
is an inevitable interference that cannot be neglected. To address this issue, this paper …

Aero-engine is a high safety requirement systems, thus the consequences of actuator faults
are often extremely serious. Considering the robustness and fault detection rate at the same …

Actuator failures and the failures of controlled objects are often considered together. To
overcome this limitation, a class of sliding mode observers for the fault diagnosis of …

This paper deals with sensor faults of aircraft engines under uncertainties using a bank of
second-order sliding mode observers (SMOs). In view of the effect of inevitable uncertainties …

In this paper, a novel sliding mode observer is proposed for systems that do not satisfy
common conditions required for fault estimation, in particular the so-called matching …

This paper investigates the actuator fault isolation problem for a class of linear systems. To
isolate the actuator faults amongst all possibilities, we first relate each possibility to a faulty …
