Economic performance assessment of two ROM ore milling circuit controllers / Donghui Wei in Minerals engineering, Vol. 22 N° 9/10 (Août/Septembre 2009) 

Public ISBD [article]  in Minerals engineering > Vol. 22 N° 9/10 (Août/Septembre 2009) . - pp. 826–839 Titre : Economic performance assessment of two ROM ore milling circuit controllers Type de document : texte imprimé Auteurs : Donghui Wei, Auteur ; Ian K. Craig, Auteur Année de publication : 2009 Article en page(s) : pp. 826–839 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : Mineral  processing  Mineral  economics  Particle  size  Grinding  Flotation  Process  control Résumé : Economic performance assessment of control systems is receiving increasing attention in both academia and industry. A relevant framework is proposed in Bauer and Craig (Bauer, M., Craig, I.K., 2008. Economic assessment of advanced process control – a survey and framework. Journal of Process Control 18 (1), 2–18) based on a comprehensive survey of the methods for economic analysis of advanced process control systems. The framework provides a formal procedure for the economic assessment of control systems. A practically motivated simulation study is used to cast the economic performance assessment of a nonlinear model predictive controller and three single-loop PID controllers for a run-of-mine milling circuit into this framework. Performance functions of the milling circuit, which dynamically relate the circuit process variables to monetary values, are developed based on a survey study on milling circuits and an in-depth literature study.
