Combined Petri Net Controller for Discrete Event Systems
Wei Wu · Acta Automatica Sinica · 2003
This paper addresses the problem of controller synthesis of discrete event systems (DES) modeled by controlled Petri nets (PN) with uncontrollable transitions. The combined PN controller for DES proposed has both the virtues of the mapping controller and the compiled one,that is,it combines the advantages of the compiled controller in the aspect of obtaining and tracing system state and the mapping controller in the aspect of implementing of control action. Examples are used to illustrate the design method of the combined PN controller.
