Abstract

With supervisory control theory it is possible to describe controllers which influence the behaviour of a system by disabling controllable events But sometimes it is desirable to have a controller which not only disables controllable events but also chooses one among the enabled ones This event can be interpreted as a command given to the plant This idea is formalized in the concept of an implementation which is a special supervisor enabling at most one controllable event at a time In this paper some useful properties are introduced which ensure when met that each implementation of a given DES is nonblocking The approach is applied to a simple chemical batch process example
