Discrete event supervisor design and application for manufacturing systems with arbitrary faults and repairs
Ayse Nur Acar, Ece Güran Schmidt · 2015
This paper considers the supervisory control of discrete event systems (DES) that are subject to faults. To this end, an existing method for the fault-recovery and repair of single faults is extended to the case of different faults. As a result, we obtain a supervisor that follows the specified nominal system behavior in the fault-free case, converges to a desired degraded behavior for each fault type and recovers the nominal behavior after repair. The results of the paper are illustrated by a small example.
