Effective fault detection, estimation, and isolation are essential for the safety and reliability of
gas turbines. In this article, a hybrid fault detection and isolation (FDI) approach is presented …

Considering the fact that the signs of performance deterioration in the main components of
gas turbines vary in different operating points, thus designing a Fault Detection and …

This study proposes a model-based robust fault detection and isolation (RFDI) method with
hybrid structure. Robust detection and isolation of the realistic faults of an industrial gas …

Fault diagnosis plays a significant role in conducting condition-based maintenance and
health management for gas turbines (GTs) to improve reliability and reduce costs. Various …

In this paper, a multiple model (MM)-based detection and estimation scheme for gas turbine
sensor and gas path fault diagnosis is proposed, which overcomes the coupling effects …

Abstract Gas Turbine Engines (GTEs) are vastly used for generation of mechanical power in
a wide range of applications from airplane propulsion systems to stationary power plants …

Health condition monitoring of Gas Turbine Engine (GTE) components is key for predictive
maintenance planning. The task is challenging, as the gas-path components are mostly …

Sensor faults can cause incorrect estimations of gas path fault amplitudes in gas turbines. In
this paper, an unscented Kalman-filter (UKF)-based simultaneous diagnostic scheme for gas …

A classifier trained by a normalized simulation parameter could not identify an actual fault. In
order to solve this problem, improved data preprocessing is proposed which normalizes the …

The working environment of hot components is the most adverse of all gas turbine
components. Malfunction of hot components is often followed by catastrophic …
