CONTROL ENGINEERING PRACTICE 2013年第11期21卷 1608-1619页

作者： Bonfe, Marcello Fantuzzi, Cesare Secchi, Cristian Univ Ferrara ENDIF I-44122 Ferrara Italy Univ Modena & Reggio Emilia DISMI I-42122 Reggio Emilia Italy

The paper presents the application of object-oriented modeling techniques to control software development for complex manufacturing systems, with particular focus on case studies taken from the packaging industry and design patterns that can be abstracted from such case studies. The proposed methodology for control software modeling and implementation is based on a practical approach refined on the basis of on-the-field experience and interactions with control engineers involved in the development projects. The final objective of the paper is to review and analyze patterns for the solution of design and implementation issues that typically arise in the considered application domain.

引用

IFAC Proceedings Volumes 2013年第9期46卷 2191-2196页

作者： A.A. Isakov Distributed Computing and Networking Department St. Petersburg State Polytechnical University St. Petersburg Russia

OpenMVL Project is considered by author as the starting point of discussion and the first executed step in the direction of the new standard for tools for modeling and simulation of complex dynamical systems (CDS). OpenMVLShell is the open source software for comparison different approaches to the problem of designing modern environments for CDS modeling and simulation first of all. However it may be used in Education too as its analog OpenModelica. OpenMVLShell is based on object-Oriented modeling (OOM) approach and uses Model Vision Language (MVL) suggested by MvStudiumGroup. MVL is object-oriented language for modeling and simulation of hierarchical multi-component systems with event-driven behavior based on differential-algebraic equations (hybrid systems). Possibilities of OpenMVLShell are illustrated by two examples. The first one demonstrates how to use OpenMVLShell for comparison different DAE solves. The second one illustrates using OpenMVLShell in “modeling and Simulation” course as instrument of active learning.

COMPUTER APPLICATIONS IN ENGINEERING EDUCATION 2010年第1期18卷 53-66页

作者： Calvo, I. Marcos, M. Orive, D. Sarachaga, I. Univ Basque Country ETSI Bilbao Dept Automat Control & Syst Engn Bilbao 48013 Spain

The interaction with real plants is a key issue in control engineering. education in order to consolidate the concepts learned in the classroom. Unfortunately, for several reasons, real laboratories are not always available. On the other hand, Internet technologies have proved to be mature and reliable, becoming a common alternative in the creation of remote laboratories. However, the use of these technologies in complex remote laboratories is not a trivial task as several requisites must be satisfied simultaneously. This article proposes a methodology that eases the creation of remote laboratories establishing the steps to build up a remote access system, This methodology proposes a set of key components that can be used to define the access to a remote plant from a functional point of view. Some of these components are generic being reusable in most applications whereas others are application specific. in summary, the methodology allows designers to concentrate more on the functionality of the applications than on the technical aspects Of the underlying technology. The use of this methodology is illustrated with a relatively complex example A laboratory manufacturing cell. (C) 2009 Wiley Periodicals, Inc.

A Hybrid object-Oriented Library for the Simulation of Sugar Houses

引用

IFAC Proceedings Volumes 2009年第17期42卷 92-97页

作者： Rogelio Mazaeda César de Prada Alejandro Merino Felipe Acebes System Engineering and Automation Department. Science Faculty University of Valladolid. Paseo del Prado de la Magdalena. S/N. Valladolid. Spain

The final department of any sugar factory is in charge of producing commercial sugar grains out of an impure sucrose in water solution by means of crystallization. Quality requirements demand a fed-batch mode of operation from most of the process units of the section and in particular from the industrial crystallizers. A library of reusable simulation models of the Sugar House have been developed taking advantage of object oriented modeling concepts. The dynamic simulation of batch equipment usually demands the use of hybrid type models.

COMBINING UML WITH IEC 61131-3 LANGUAGES TO PRESERVE THE USABILITY OF GRAPHICAL NOTATIONS IN THE SOFTWARE DEVELOPMENT OF COMPLEX AUTOMATION SYSTEMS

引用

IFAC Proceedings Volumes 2007年第16期40卷 90-94页

作者： Uwe Katzke Birgit Vogel-Heuser Member IEEE University of Kassel Germany

The visual presentation of the software standard IEC 61131-3 for embedded automation systems can hardly impart the structures of complex solutions. The UML as an alternative presentation from conventional software is confusing the engineers of this domain, as it contains many diagrams and notation details, which are designed for other purposes. The UML for Process Automation (UML-PA) offers a customized subset of the UML, which simplifies the graphical structure of the UML. Ambiguous notations elements of the UML are supplemented or cleared. UML-PA refers to IEC 1131-3 behavior specifications to offer skilled familiar notations within the framework of new structures.

MANUFACTURING APPLICATION INTEGRATION SCHEME USING ISO 15745 AND IEC 62264

引用

IFAC Proceedings Volumes 2005年第1期38卷 52-57页

作者： Emmanuel delaHostria Rockwell Automation Mayfield Heights Ohio U.S.A.

A common challenge in the integration of processes, resources, and information exchanges across manufacturing operations within an enterprise involves selecting resource interfaces to support interoperability of the operations. By combining the integration approaches of ISO 15745 (application integration framework) and of IEC 62264 (enterprise-control system integration), a scheme to delineate these interoperability interfaces is proposed. The scheme extends the IEC 62264 generic activity model beyond the manufacturing operations management domain and the ISO 15745 integration model beyond the operations automation domain.

A software environment task object-oriented design (ETOOD)

引用

JOURNAL OF SYSTEMS AND SOFTWARE 2002年第2期60卷 129-140页

作者： Tabary, D Abed, M CNRS UMR 8530 Lab Automat & Mecan Ind & Humaines F-59313 Valenciennes 9 France

This paper is intended to present an approach to the construction of a task model of method, named task object-oriented design (TOOD), used for the development of an interactive system. This approach is based on a formal notation, giving quantitative results which may be checked by designers and which provide the possibility of performing mathematical verifications on the models. The modeling formalism is based on the joint use of the object approach and of high-level Petri nets. The concepts borrowed from the object approach make it possible to describe the static aspect of tasks and the Petri nets enable the description of dynamics and behavior. We also describe a software aid tool for the manipulation of these models, which allow the editing of a task model. In order to facilitate comprehension of the method, a simple example of procedure used in missile firing management will be given. (C) 2002 Elsevier Science Inc. All rights reserved.

Safe object oriented programming of distributed real time systems in PEARL

引用

COMPUTER SYSTEMS SCIENCE AND ENGINEERING 2002年第2期17卷 85-94页

作者： Halang, WA Pereira, CE Frigeri, AH Fern Univ Hagen Fac Elect Engn D-58084 Hagen Germany Univ Fed Rio Grande Sul Dept Elect Engn Porto Alegre RS Brazil

An object oriented extension of the real time programming language PEARL is presented, which preserves PEARL's expressiveness for timeliness and industrial processes and, at same time, improves the language's readability and manageability through the adoption of a better encapsulation paradigm derived from the object concept. The resulting object model allows the definition of inter- and intraobject parallelism in a transparent and simple way. Some extensions aim to enhance testability and safety related aspects of the language, such as the enforcement of a deterministic temporal behaviour. The proposed language is fully backward compatible with PEARL 90, while allowing powerful abstraction concepts.

Reference Models to Design Automation System for Manufacturing Lines

引用

IFAC Proceedings Volumes 2001年第17期34卷 93-98页

作者： Luca Ferrarini Dipartimento di Elettronica e Informazione Politecnico di Milano P.za L da Vinci 32 20133 Milano fax +39 2 2399 34 12

The problem of the design of the control system functions for automated manufacturing lines is addressed. In particular, a modeling framework is proposed which is based on proper hierarchical composition, formal representations, and compliance with international control standards for logic control. The object-oriented modeling technique has been exploited for the definition of two basic reference models, one for the plant to be controlled and one for the control functions. The results here proposed are particularly useful in the perspective of the design process. The paper shows the application of such concepts to an industrial serigraph line for glasses.

引用

IFAC Proceedings Volumes 2000年第7期33卷 135-141页

作者： F. Bordeleau M.A. Cloutier D. Biagé School of Computer Science Carleton University Ottawa Canada CML Versatel Hull Canada

The migration from a conventional non-object-oriented to an object-oriented development process is a mission that must be carefully planned. In this paper, we relate the experience of CML Versatel in conducting such a migration. More specifically, we: discuss the planning of the migration, describe the object-oriented development process used in this project, give an overview of how the process works on a day-to-day basis, discuss the experience of CML Versatel of making the migration to and using a new object-oriented development process, and define goals for improving the process.
