Abstract:
The concept of fuzzy reasoning has been extended to Petri
nets and has been applied for modeling of discrete event
systems [1]. However, the theory was not extended to
supervisory control of discrete event systems because there
is no valid translation for fuzzy Petri nets into ladder
logic diagrams. Discrete event systems are time and event
dependent and hence digital in nature. However, discrete
systems like batch reactors, flexible manufacturing systems
require representation in modeling in terms of degree of
truth. This representation, although enabled by fuzzy Petri
nets has not been carried over to Programmable Logic
Controller (PLC) for implementation. This paper1 suggests an
algorithm to execute fuzzy Petri net formalism and then to
implement it through Programmable Logic Controllers.
Keywords:
Fuzzy Petri net, Ladder Logic Diagrams, Supervisory Control,
PLC.
