Time-trajectory based Active Fault-Tolerant Control

IFAC Proceedings Volumes, 2012
In this note, we present a model-free approach to solve an active fault-tolerant control problem in the behavioral framework. In our control structure, we do not require an explicit fault diagnosis module that identifies the complete fault information. Instead, a new controller is designed based only on the measurements generated by the system in real ...

A sliding‐mode‐based active fault‐tolerant control for robust trajectory tracking in quad‐rotors under a rotor failure

International Journal of Robust and Nonlinear Control, 2022
In this article an active fault‐tolerant control (FTC) is developed for the tracking problem in a quad‐rotor under the effects of a rotor failure and external disturbances.

Active Fault-Tolerant Control of a Double Inverted Pendulum

IFAC Proceedings Volumes, 2006
This paper proposes an active fault-tolerant control scheme based on a gain-scheduled H∞ design strategy. Under the assumption that the effects of faults on the system can be of affine parameter dependence, a reconfigurable robust H∞ controller is developed.

A Neural Adaptive Approach for Active Fault-Tolerant Control Design in UAV

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2020
Faults in aircraft actuators can cause serious issues in safety. Due to the autonomous nature of the unmanned aerial vehicles (UAVs), faults can lead to more serious problems in these systems.

ACTIVE FAULT-TOLERANT CONTROL FOR UNSTABLE SYSTEMS

IFAC Proceedings Volumes, 2006
Abstract This paper concerns active fault-tolerant control (FTC) for unstable systems. A major obstacle to this problem is that the time delay between the fault appears and the FTC controller becomes active may destabilize the system. In this paper, an active FTC scheme based on gain-scheduled H-infinity controller and neural network is proposed ...

A graphical active fault tolerant control approach

2015 16th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA), 2015
A fault tolerant control synthesis is a key solution for great and several issues which threat system safety and may have critical and dangerous consequences especially in aeronautics, medicines and chemical industry. This is why, in this present work, an Active Fault Tolerant Control (AFTC) framework is designed using a linear adaptive observer-based ...

A Novel Framework of Cooperative Design: Bringing Active Fault Diagnosis Into Fault-Tolerant Control

IEEE Transactions on Cybernetics, 2022
Fault-tolerant control (FTC) may conceal fault symptoms, thereby increasing the difficulty of fault diagnosis (FD). In this article, a novel framework for the cooperative design of active FD and FTC is proposed to optimize FD performance while ...
