Performance evaluation in active fault tolerant control systems

Proceedings of the 2005 IEEE International Symposium on, Mediterrean Conference on Control and Automation Intelligent Control, 2005., 2005
In this paper, we address the problem of incorporating the notions of performance evaluation and degraded mode operation in an active fault tolerant control system (AFTCS) scheme. This problematic is addressed under a multi-criterion optimization framework, which allows us to consider several design performances.

Active and passive fault-tolerant LPV control of wind turbines

Proceedings of the 2010 American Control Conference, 2010
This 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

Model-free active fault tolerant control for sensor fault

2024 10th International Conference on Control, Decision and Information Technologies (CoDIT)
International audienceAn active model-free sensor fault tolerant control approach is presented in this paper. The proposed method is based on a model-free controller that has demonstrated an effective ability to work without any analytical model ...

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 ...

Active fault tolerant control with actuation reconfiguration

IEEE Transactions on Aerospace and Electronic Systems, 2004
This paper presents an integrated approach to fault detection, isolation, and fault tolerant control (FTC). In the proposed approach a constrained Kalman filter based fault detection and isolation (FDI) method (Larson et al., 2002) is modified to reduce its computation load and then applied to detect and isolate a faulty actuator or sensor.

Active fault tolerant control of a flexible beam

SPIE Proceedings, 2007
This paper presents the development and application of an H∞ fault detection and isolation (FDI) filter and fault tolerant controller (FTC) for smart structures. A linear matrix inequality (LMI) formulation is obtained to design the full order robust H∞ filter to estimate the faulty input signals.

Fault tolerant control of active magnetic bearings

IEEE International Symposium on Industrial Electronics. Proceedings. ISIE'98 (Cat. No.98TH8357), 2002
A nonlinear model of a Rolls-Royce turbomachine's rotor supported by active magnetic bearings (AMBs) is presented. The model has the capability to model magnetic bearing systems of a variety of different configurations. A multiobjective genetic algorithm (MOGA) is used to design PID controllers for the AMB system with five different bearing ...

Experiments on Fault-Tolerant Active Vibration Control

Journal of Dynamic Systems, Measurement, and Control, 2008
The purpose of this work is to experimentally demonstrate a fault-tolerant active vibration control system. Active vibration control is achieved using piezoceramic sensors and actuators (transducers) that are attached to a simply supported beam. These transducers are used by a set of optimal H2 feedback compensators to minimize the lateral vibration of

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 ...

Adaptive fault tolerant control for active suspension

2016 IEEE First International Conference on Control, Measurement and Instrumentation (CMI), 2016
This paper deals an adaptive fault tolerant control for active suspension in the presence of actuator saturation. An adaptive state-feedback controller is designed to tackle the issue of actuator fault. A Disturbance observer is utilized to observe the lumped disturbance.
