Enhanced distinguishability in Supervisory Fault Tolerant Control
نویسندگان
چکیده
This paper deals with the design of an estimator-based supervisory Fault Tolerant Control (FTC) scheme for Linear Time Invariant (LTI) systems. A formal stability proof based on dwell-time conditions is presented when the state of the detection filter does not correspond to the plant state, as in classical (Luenberger) observer-based approaches. In this context, fault isolability could be improved leading to an enhanced distinguishability between all possible operating modes. Note that this paper should be understood like a preliminary work to provide a unified context for a norm-based performance optimization problem. The efficiency of the proposed technique is illustrated on a numerical example. Copyright © 2014 IFAC

Supervisory fault tolerant control with integrated fault detection and isolation: A switched system approach
This paper focuses on supervisory fault tolerant control design for a class of systems with faults ranging over a finite cover. The proposed framework is based on a switched system approach, and relies on a supervisory switching within a family of pre-computed candidate controllers without individual fault detection and isolation schemes. Each fault set can be accommodated either by one candida...
متن کاملSupervisory fault tolerant control for a class of uncertain nonlinear systems
This paper focuses on the design of an unique scheme that simultaneously performs fault isolation and fault tolerant control for a class of uncertain nonlinear systems with faults ranging over a finite cover. The proposed framework relies on a supervisory switching among a family of pre-computed candidate controllers without any additional model or filter. The states are ensured to be bounded d...
متن کاملFault-Tolerant Control of Discrete Event Systems based on Fault-Accommodating Models
Fault-tolerant control systems with discrete-event dynamics allow for differing sets of design requirements, that specify the system’s behaviour during nominal operation and in the case of component degradation or component malfunction. This paper is concerned with the design of faulttolerant control algorithms for discrete event systems in the framework of supervisory control theory. Its main ...
متن کاملFault-tolerant robust supervisor for discrete event systems with model uncertainty and its application to a workcell
This paper addresses the problem of fault-tolerant robust supervisory control of discrete event systems (DES’s) with model uncertainty. Necessary and sufficient conditions for the existence of a fault-tolerant robust supervisor are derived. If the conditions are satisfied, then tolerable fault event sequences embedded in the system can be achieved. The results obtained are applied to design, mo...
