A Model-Based Transformation Method to Design PLC-Based Control of Discrete Automated Manufacturing Systems
نویسندگان
چکیده
In the domain of Automated Manufacturing Systems (AMS), Supervisory Control Theory (SCT) is a general modelbased framework, which contributes to the automated development of control systems. Although, SCT delivers important theoretical insights to deal with controllers design, its use in the industry is still weak, because of the discrepancy among its abstract controllers and their physical implementation. Whithin this context, this paper presents a practical method to automatically produce distributed supervisory control of AMS in the form of Grafcet, which is a graphical modelling tool widely used to specify controllers dynamic behaviors. This method is built to evaluate an authors’ previous distributed approach to control synthesis and implementation. It is based on Modelto-Model (M2M) transformations implemented in a java/EMF environment. An experimental AMS illustrates its purposes.

A stepwise method for identification of controlled discrete manufacturing systems
This paper deals with the identification of discrete event manufacturing systems that are automated by a programmable logic controller (PLC). The behaviour of the closed loop system (PLC and Plant) is observed during its operation and is represented by a single long sequence of observed input/output signals vectors. The proposed method follows a blackbox and passive identification approach; it ...

As business environments are rapidly changing, the manufacturing system must be reconfigured to adapt to various customer needs. In order to cope with this challenge, it is quintessential to test industrial control logic rapidly and easily in the design time, and monitor operational behavior in the run time of automated manufacturing system. Proposed integrated model for virtual prototyping and...
متن کاملRetrieval–travel-time model for free-fall-flow-rack automated storage and retrieval system
Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...
