Fault-tolerant supervisory control of discrete-event systems

Fault-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 ...

Partial Observation in Distributed Supervisory Control of Discrete-Event Systems

Distributed supervisory control is a method to synthesize local controllers in discrete-eventsystems with a systematic observation of the plant. Some works were reported on extending this methodby which local controllers are constructed so that observation properties are preserved from monolithic todistributed supervisory control, in an up-down approach. In this paper, we find circumstances in ...

A fault tolerant architecture for supervisory control of discrete event systems

In this paper the problem of Fault Tolerant Control (FTC) in the framework of Discrete Event Systems (DES) modeled as automata is considered. The approach we follow is the so-called active approach in which the supervisor actively reacts to the detection of a malfunctioning component in order to eventually meet degraded control specifications. Starting from an appropriate model of the system, w...
