A Realization and Verification of A Parallel Image Processing Controller by using An Extended Petri net

چکیده

We describe a case study of the design and verification of a parallel image processing unit based on an extended Petri net, which is called a Logical Colored Petri net (LCPN). This is suitable for Flexible-Manufacturing System (FMS) modeling and discussion of structural properties. LCPN is another family of colored p/t-net (CPN) with the addition of the following features: integer value assignment of marks, representation of firing conditions as marks' value based formulae, and coupling of output procedures with transition firing. Because the concept of transition firing evaluation orders is omitted from the analysis in conventional CPN, we introduce this concept formally in our proposed net. Therefore, to study the behavior of a system modeled with this net, we provide a means of searching the reachability tree for markings. Finally, we describe a case study of the design and verification for a process controller of an FMS based on the theory of this net.

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...

Mapping Sequence diagram in Fuzzy UML to Fuzzy Petri Net

This ability in fuzzy UML, practically leaves the customers and market’s need without response in this important and vital area. Here, the available sequence diagrams in fuzzy UML will map into fuzzy Petri net. However, the formal models ability will be added to the Semi-formal fuzzy UML. This formalization will add the automatic processing ability to the Semi-formal fuzzy UML. Further more, t...

Transforming Fuzzy State Diagram to Fuzzy Petri net

UML is known as one of the most common methods in software engineering. Since this language is semi-formal, many researches and efforts have been performed to transform this language into formal methods including Petri nets. Thus, the operation of verification and validation of the qualitative and nonfunctional parameters could be achieved with more ability. Since the majority of the real world...

Autonomous Parallel Parking of a Car Based on Parking Space Detection and Fuzzy Controller

This paper develops an automatic parking algorithm based on a fuzzy logic controller with the vehicle pose for the input and the steering angle for the output. In this way some feasible reference trajectory path have been introduced according to geometric and kinematic constraints and nonholonomic constraints to simulate motion path of car. Also a novel method is used for parking space detec...
