A Survey on Fault-Tolerant Supervisory Control
Mohammad Karimadini, Ali Karimoddini, Abdollah Homaifar · 2018
System fault occurrences are arbitrary, costly, and at times deadly. Therefore, it is important to systematically and robustly react to occurred faults in a timely manner to recover the system. In this paper, we survey the notion of fault in supervisory control of discrete event systems. This paper particularly reviews the results on fault-tolerant supervisory control, robust supervisory control and reliable supervisory control in order to investigate the functionality of distributed discrete event systems in faulty conditions. The insights help the designers to understand under what faulty conditions a cooperative supervisory control scheme remains valid and how to synthesize the supervisory control of discrete event systems as fault-tolerant as possible.
