A Petri net based supervisory control implementation
Jana Flochová · 2004
The paper presents an implementation of supervisory controllers in the IEC 61131-3 compliant programming environment. The implemented model-based approaches provide particularly simple methods for constructing feedback controllers for untimed and timed discrete event systems modeled by Petri nets. Programs written in Matlab 5.3/6.1 have been used to solve the OFFLINE supervisory control synthesis and supervisor simulation. The implementation of the designed supervisory controller can be performed in an IEC 61131-3 compliant programming environment with help of a quick PLC controller, or a quick dedicated controller.
