discrete event systems (DES) whose structures change as they develop in different …

Process tracking by equivalent states in modal supervisory control

G Faraut, L Piétrac, E Niel - ETFA2011, 2011 - ieeexplore.ieee.org
This paper proposes an extension of the process tracking in modal supervisory control that
takes into account the models of the controlled processes which are not trimmed. Indeed, in …

Discovering data-aware mode-switching constraints to monitor mode-switching decisions in supervisory control
