Simplification of a Petri Net controller in industrial systems
This paper deals with the problem of forbidden states in discrete event systems modeled by Petri Net. To avoid the forbidden states, some constraints which are called Generalized Mutual Exclusion Constraints can be assigned to them. Enforcing these constraints on the system can be performed using control places. However, when the number of these constraints is large, a large number of control p...
متن کاملImplementation of Petri Nets Based Controller using SFC
This paper presents a method for implementing a controller synthesized by PN-based SCT theory. Despite the great acceptance of SCT in controller design, there are problems with its practical implementation. Sequential Function Chart, as an international standard programming language, is used for implementing PN-based controllers. One problem in the implementation step is the occurrence of simul...

متن کاملController Design for Petri Net with Uncontrollable Transition
IA Petri net controller method for Petri net model with uncontrollable transitions that enforces the conjunctions a set of linear inequalities on the Parikh vector or place markings is proposed. The method for constructing a Petri net feedback controller is based on part design and Petri net reduction technique. Constraints are classified into admissible and inadmissible constraints. Matrix-Tra...
