            Abstract : 
We study the supervisory control of nondeterministic discrete event dynamical systems (DEDS´s) with driven events in the setting of prioritized synchronization and trajectory models introduced by Heymann (1990, 1991). Prioritized synchronization captures the notions of controllable, uncontrollable, and driven events in a natural way, and we use it for constructing supervisory controllers. The trajectory model is used for characterizing the behavior of nondeterministic DEDS´s since it is a sufficiently detailed model (in contrast to the less detailed language or failures models), and serves as a language congruence with respect to the operation of prioritized synchronization. We obtain results concerning controllability and observability in this general setting
