This research addresses problems associated with the design and                 analysis of discrete-event (DE) supervisory controllers of continuous-          time (CT) systems (hybrid systems) often encountered in manufacturing           situations and distributed computing.  The approach involves                    development of a modeling methodology and representational forms of             hybrid systems which permit straight-forward simulation and analysis            of such hybrid systems.  Appropriate mathematical structures for the            analysis and design of these hybrid systems are developed.  Petri-Nets          (PNs) serve as the starting point for the modeling of the DE                    controller component and classical state model (geometric) control              theory techniques are developed for the CT component of the hybrid              systems.  Modifications to existing PN and CT modeling methodologies            address several key problems associated with hybrid systems including           characterization of information flow within the hybrid model and                between the CT and DE systems.  The new modeling technique will permit          meaningful re-interpretation of classical PN properties and CT system           properties.
