Modelling and control of large-scale systems via hybrid Petri Nets

Hybrid Petri Nets are suitable to model and control significant classes of large-scale systems, such as manufacturing processes and transportation networks, which can have the structure of hybrid systems. A hybrid Petri net (HPN) is a combination of a `classical´ Petri net and a continuous Petri net, the `fluid´ version of a timed Petri net. In the proposed model, the discrete part of the HPN `regulates´ the continuous Petri net by managing the events resulting in changes to the system behaviour, so as to cope with the new conditions and still pursue the control objectives.
