Unfalsification based Fault Tolerant Controller
ETFA2011, 2011Unfalsified 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 ...

Robust fault-tolerant controller design
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012A robust fault-tolerant control scheme using an accurately-identified model of a plant operating in closed-loop is proposed. Parametric uncertainties are restricted to the subsystems which are likely to vary and do not apply to the entire system. A good accuracy of the parameter estimation scheme is obtained by ensuring that the identified model set ...

Fault-tolerant control systems — A holistic view
Control Engineering Practice, 1997Abstract Fault-tolerant control is used in systems that need to be able to detect faults and prevent simple faults related to control loops from developing into production stoppages or failures at a plant level. This is obtained by combining fault detection with supervisory control and re-configuration to accommodate faults.

Ultrareliable fault-tolerant control systems
Digital Avionics Systems Conference, 1984It is demonstrated that fault-tolerant computer systems, such as on the Shuttles, based on redundant, independent operation are a viable alternative in fault tolerant system designs. The ultrareliable fault-tolerant control system (UFTCS) was developed and tested in laboratory simulations of an UH-1H helicopter.

Actuator Fault Tolerant PID Controllers
IFAC Proceedings Volumes, 2012Abstract This paper deals with issues of actuator fault tolerant PID controllers. It is studied, how residual generation based on a linear model is affected by the robust properties of a PID used in feedback. To get the sensitivity of the residual with respect to faults and to keep the robustness of the controller, a scheme is proposed with a non ...

Fault Tolerant Feedback Control
2001An architecture for fault tolerant feedback controllers based on the Youla parameterization is suggested. It is shown that the Youla parameterization will give a residual vector directly in connection with the fault diagnosis part of the fault tolerant feedback controller. It turns out that there is a separation be-tween the feedback controller and the

Coverage in fault-tolerant control
Automatica, 2004This 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-tolerant Control Systems
1999Fault tolerant control offers enhanced availability and reduced risk of safety hazards when component failure and other unexpected events occur in a controlled plant. Fault-tolerant control merges several disciplines into a framework with common goals.
