This paper deals with supervisory control of discrete event systems (DES) by state feedback in order to avoid uncontrollable specifications and blockings. It incorporates two levels of modeling that includes the system and specification model and secondly the interpretation of the specification model in term of the system model based on trace equivalence. Next the controller process is computed. In...
This paper deals with supervisory control of discrete event systems (DES) modeled by interpreted Petri nets (IPN). In the approach herein proposed, both, the specification and the system model are described by IPN, however, the specification describes a state subset that the specification must reach. It also captures the order in which these states must be reached. Based on this framework, this paper...
This paper deals with a diagnosis based on interpreted Petri nets. It introduces the problem of energy interruption on electrical systems, which is a phenomenon of discrete nature where lost of the electrical energy and disconnections of several elements characterize it. Also, it presents a method for obtaining the diagnosis based on interpreted Petri nets and error interpreted Petri nets; the diagnosis...
