Coverage in fault-tolerant control

Automatica, 2004
This paper deals with a two-level framework for the analysis, design, and operation of a fault tolerant system, where the upper level is a stochastic discrete state continuous time system describing a slower failure process, and the lower level is a conventional deterministic continuous state system in which top level states are embedded as parameters.

Fault diagnostics and fault tolerant control

IEEE Transactions on Aerospace and Electronic Systems, 1998
A novel simultaneous fault detection and diagnostics (FDD) and fault tolerant control (FTC) strategy for nonlinear stochastic systems in closed loops based on a continuous stirred tank reactor (CSTR) is presented. The purpose of control is to track the reactant concentration setpoint.

Fault tolerant control of a gyroscope system

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
This paper presents an experimental study of a control moment gyroscope using a new controller architecture, generalized internal model control, which separates the controller design into two stages: (a) a nominal performance controller and (b) a robustness controller.

Fault tolerance of decentralized adaptive control

Proceedings ISAD 93: International Symposium on Autonomous Decentralized Systems, 2002
A decentralized adaptive control system, in which the local feedback gains are tuned by the sigma -modified adaptive law so as to achieve small output errors with small feedback gains, is proposed. Stability analysis and fault tolerance analysis are performed, and it is shown that if the stability of one of the stable subsystems breaks down and if the ...

Fault-tolerant control of a polyethylene reactor

Journal of Process Control, 2006
This work focuses on fault-tolerant nonlinear control of a gas phase polyethylene reactor. Initially, a family of candidate control configurations, characterized by different manipulated inputs, are identified. For each control configuration, a bounded nonlinear feedback controller, that enforces asymptotic closed-loop stability in the presence of ...

Concepts and methods in fault-tolerant control

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
Faults in automated processes will often cause undesired reactions and shut-down of a controlled plant, and the consequences could be damage to technical parts of the plant, to personnel or the environment. Fault-tolerant control combines diagnosis with control methods to handle faults in an intelligent way.

Conclusions [Diagnosis and Fault‐tolerant Control 2: From Fault Diagnosis to Fault‐tolerant Control]

2021
This chapter provides an introduction into the field of fault detection, fault diagnosis and fault-tolerant systems with methods, which have proven their performance in practical applications. The derivation of the mathematical description of technical processes is relatively mature; however, they present challenging aspects in the fields of advanced ...

Unfalsification based Fault Tolerant Controller

ETFA2011, 2011
Unfalsified Control is a data-driven, plant-mo del-free control design approach. It does not require a plant model, only measured input/output data is used, which makes it an interesting approach for the development of multi-controller structures aimed either to the control of non-linear or time-varying processes, or the implementation of Fault ...

Fault tolerant process planning and control

[1992] Proceedings. The Sixteenth Annual International Computer Software and Applications Conference, 2003
The authors develop a model for achieving reliable and high-performance control programs. The approach combines hierarchical control, inherent fault tolerance, and massive parallelism. The approach uses a fine-grain cellular automation for implementing the supervisory task of a hierarchical system.
