Control of real-time discrete event systems with hybrid controllability of events

The paper solves a real-time extension of the supervisory control problem for a class of real-time discrete event systems with hybrid components. The considered plant is parallel composition of subsystems each with guaranteed infimal delays between two subsequent output discrete events, with true parallelism, and with delayed response to input events. The delayed response depends on current state of plant. It is modelled using one integrator for each controllable event. An event is actually disabled if the value of integrator is equal or higher than “hybrid controllability” of the event. The minimally restrictive solution is presented
