Logical analysis and control of time Petri nets

The authors introduce an approach to logical analysis and control of timed systems modeled by controlled time Petri nets (CTPNs), an extension of time Petri nets (TPNs). They extend an enumerative technique for TPNs to include control inputs, resulting in the control class graph (CCG), a complete representation of the logical behavior of the timed system. They show that under event feedback every state trajectory for a CTPN corresponds to a path in the CCG, and for any path in the CCG there exists some event feedback policy for the CTPN that generates the corresponding state trajectory. They illustrate the application of these results for an example of supervisory coordination in a simple manufacturing system
