Fault-tolerant cooperative control of networked discrete-event systems

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 ...

Advanced design scheme for fault tolerant distributed networked control systems

This paper addresses the integrated design of fault tolerant distributed networked control systems (NCS). The NCS under consideration consists of two levels. At the lower level, sensors, actuators and local controllers are embedded and networked by sub-nets. They coordinated and supevised by the control stations located at the higher level. The core of the design scheme is the integrated design...

A Learning-based Active Fault-tolerant Control Framework of Discrete-event Systems

A fault-tolerant controller is a controller that drives the plant to satisfy control specifications under both nominal operation and after the occurrence of faults. This paper introduces a framework that ensures the fault-tolerance of a discrete-event system (DES) plant, which includes: (i) a nominal supervisor with respect to the nominal plant to ensure the control specification that is prior ...
