11、 AMANIPLA.book Page vi Thursday, January 15, 2009 10:26 AMviiThe O3neida Publications Series This book is one of a series of books to be produced within O3neida on varioussubjects related to distributed automation.O3neida is a Canadian not-for-profit corporation. O3neida Europe is a not-for-profit a

12、ssociation headquartered in Brussels, Belgium. Together they formthe hub of the O3neida networks. Their joint mission is to operate as a networkof networks fostering the development and deployment of distributed industrialautomation technologies based on open standards. These standards include,among

13、 others, the Foundation for Intelligent Physical Agents (FIPA), theDevice Profile for Web Services (DPWS), Web Crawler (WC), and Interna-tional Electrotechnical Commission (IEC) 61131 and 61499.This book contains a collection of papers focused on the simulation, diag-nosis, modeling and predictive c

14、ontrol of complex industrial systems. Thesepapers have been developed under the aegis of ANIPLA, the national automa-tion association of Italy, which celebrated its 50th anniversary in 2006.ANIPLA, Associazione Nazionale Italiana Per LAutomazione, thenational automation association of Italy, was fou

15、nded in 1956. It is a scientificnon-profit association, whose mission is to promote the discussion, dissemina-tion and education on the technological, industrial, application-oriented andsocial aspects related to automation. Its main technical services include organi-zation of workshops, courses, co

16、ngresses, journal papers, and books.ANIPLA is the meeting point of different competencies and know-howstemming from Industry, Research Institutes and Universities across a widerange of different application areas. ANIPLAs overall objective is to give com-petitive advantage to the extent possible, to

17、 automation-related enterprises inall Italian industrial sectors. Within this book, there is a strong focus on the real-time monitoring andcontrol of energy production and delivery systems and on the application ofinnovative approaches ranging from the predictive control of a gasoline engine,through

18、 fuzzy inference applied to quality control in the paper industry and upto innovative load shedding and demand management in national electricalgrids. This book will be of interest to practitioners within the automation field,particularly those focused on energy systems. It will also be of interest

19、to aca-demics and students seeking an overview of current thinking in this field orlooking for detailed treatment of any of the issues covered by the individualchapters.ch00a2_O3 desc.fm Page vii Thursday, January 15, 2009 10:41 AMviii The O3neida Publications Series More than forty authors from cou

20、ntries around the world have contributedto the production of this unique book and O3neida thanks them, one and all, fortheir strong collaboration in producing this excellent compendium and for theircontinuing contribution to the advancement of automation process control.Future volumes in the O3neida

21、/ISA series on automation will addressother equally pressing issues such as Ethernet Safety Devices and also Ontolo-gies. O3neida will also publish materials on automation objects as part of thisseries.Finally, this book is the result of a concerted effort by many O3neidamembers. I thank them all fo

22、r their dedication and commitment to O3neida asvolunteers. I particularly thank Luca Ferrarini from Polimi in Milan, Italy forleading this effort and Allan Martel, O3neida Chief Operating Officer, for coor-dinating and managing the development of the O3neida series of books on dis-tributed automatio

23、n.I also thank ISA for their interest and support in making the publicationand distribution of this important book possible.Antonio ValentiniChief Executive OfficerO3neidach00a2_O3 desc.fm Page viii Thursday, January 15, 2009 10:41 AMixTable of ContentsList of Figures xviiList of Tables xxv1 Remote
