Fault-tolerant PID controllers using a passive robust fault diagnosis approach
Control Engineering Practice, 2000Abstract Automatic controlled systems are susceptible to faults. Faults can be amplified by closed loop control systems, and they can cause a malfunction of the loop. The closed loop may alternatively hide a fault from being observed until the plant eventually reaches a state in which loop failure is inevitable.

Passive Fault-Tolerant Control of a Fixed-Wing UAV Based on Model-Free Control
2021 5th International Conference on Control and Fault-Tolerant Systems (SysTol), 2021Fixed-wing UAVs show a high interest and high challenges in control, fault diagnostic, and fault-tolerant control. Accurate models of highly coupled nonlinear systems as the Fixed-Wing UAV are complex and time consuming. A need to find a control architecture independent of the model, suitable for nonlinear systems and can reject disturbances is highly ...

Active and passive fault tolerant control allocation strategy for nonlinear systems
Journal of Vibration and Control, 2022This article introduced fault-tolerant control (FTC) schemes for over-actuated affine non-linear uncertain systems. The proposed methodologies incorporate two different control allocation (CA) units with high-level nonlinear adaptive sliding mode control (NLASMC) strategy. The first FTC strategy is active that utilizes an online CA unit to effectively

Active and Passive Fault-Tolerant LPV Control of Wind Turbines
Proceedings of the 2010 American Control Conference, 2010This paper addresses the design and comparison of active and passive fault-tolerant linear parameter-varying (LPV) controllers for wind turbines. The considered wind turbine plant model is characterized by parameter variations along the nominal operating trajectory and includes a model of an incipient fault in the pitch system. We propose the design of

Passive supervisor for railway fault-tolerant Ethernet networked control systems
ETFA2011, 2011In this study, OPNET simulations are run to study the performance of a single Gigabit Ethernet two-wagon train control network. The network carries both control and entertainment loads. Each wagon has two servers; a Controller to carry the control load and an Entertainment Server to carry the entertainment load.

Robust Passive Fault Tolerant Control Applied to Jet Engine Equipment
PHM Society European Conference, 2014In order to minimize the occurrence of unexpected costly flight failures modern aircraft engines industry focuses especially on increasing product’s availability. In this work, we propose to monitor the health of a Variable Stator Vane (VSV), subsystem controlling the amount of airflow through the High Pressure Compressor (HPC), allowing optimum ...

Passive Fault Tolerance for a Magnetic Bearing Under PID Control
Volume 4: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award, 2001NASA Glenn Research Center (GRC) has developed a Fault-Tolerant Magnetic Bearing Suspension rig to enhance the safety of the bearing system for multiple component failures. A simple proportional-integral-derivative (PID) controller with no fault detection mechanisms was tested in a passive way where the initial bias current and control gains for all ...

Design of passive fault tolerant control of a process system
The 27th Chinese Control and Decision Conference (2015 CCDC), 2015Fault tolerant control strategies are classified into active tolerant control and passive tolerant control. When an efficient fault diagnosis procedure is difficult to be obtained, a passive tolerant control strategy is a realistic choice. This paper introduces an example of passive tolerant control system design which take into account the priori ...
