Hybrid fault detection and isolation strategy for non-linear systems in the presence of large environmental disturbances
(
Institution of Engineering and Technology
, 2010 , Article)
The problem of designing and developing a hybrid fault detection and isolation (FDI) scheme for a non-linear system that is subject to large environmental disturbances is investigated. In the proposed FDI scheme, a hybrid ...
A component map tuning method for performance prediction and diagnostics of gas turbine compressors
(
Elsevier Ltd
, 2014 , Article)
In this paper, a novel compressor map tuning method is developed with the primary objective of improving the accuracy and fidelity of gas turbine engine models for performance prediction and diagnostics. A new compressor ...
A single dynamic observer-based module for design of simultaneous fault detection, isolation and tracking control scheme
(
Taylor and Francis Ltd.
, 2018 , Article)
The problem of simultaneous fault detection, isolation and tracking (SFDIT) control design for linear systems subject to both bounded energy and bounded peak disturbances is considered in this work. A dynamic observer is ...
Distributed reconfigurable control strategies for switching topology networked multi-agent systems
(
ISA - Instrumentation, Systems, and Automation Society
, 2017 , Article)
In this paper, distributed control reconfiguration strategies for directed switching topology networked multi-agent systems are developed and investigated. The proposed control strategies are invoked when the agents are ...
A Dual Particle Filter-Based Fault Diagnosis Scheme for Nonlinear Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
In this paper, a dual estimation methodology is developed for both time-varying parameters and states of a nonlinear stochastic system based on the particle filtering scheme. Our developed methodology is based on a concurrent ...
Ensemble Kalman Filters for State Estimation and Prediction of Two-Time Scale Nonlinear Systems with Application to Gas Turbine Engines
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this brief, we propose and develop estimation, prediction, and health monitoring methodologies for nonlinear systems by modeling the damage and degradation mechanism dynamics as 'slow' states that are augmented with the ...
A dendritic cell immune system inspired scheme for sensor fault detection and isolation of wind Turbines
(
IEEE Computer Society
, 2018 , Article)
In this paper, a fault detection and isolation (FDI) methodology based on an immune system (IS) inspired mechanism known as the dendritic cell algorithm (DCA) is developed and implemented. Our proposed DCA-based FDI ...
Integrated design of fault detection, isolation, and control for continuous-time Markovian jump systems
(
John Wiley and Sons Ltd
