Sequential Control Algorithm in the Form of Fuzzy Interpreted Petri Net
Lesław Gniewek · IEEE Transactions on Systems Man and Cybernetics Systems · 2012
Fuzzy Petri nets (PNs) discussed in the literature are usually considered as expert systems involving fuzzy-based reasoning. They are used as decision support or monitoring systems. There were only few ideas of using fuzzy PNs directly as controllers. This paper defines fuzzy interpreted PN, which can be a formal representation of a concurrent control algorithm. Hardware implementation of the net, which uses fuzzy RS flip-flops and fuzzy gates, is proposed. The usefulness of the net for control algorithm description is exemplified by a hot forging process.
