On controllable predicates and languages in discrete-event systems
Toshimitsu Ushio · 2003
In discrete-event systems two control techniques, called supervisory control and state feedback logic, have been proposed. It is shown that controllability of the legal language for a given predicate is equivalent to that for the corresponding reachability set. The relationship between the supremal controllable subpredicate of the predicate and the supremal controllable sublanguage of the corresponding legal language is then dealt with.>
