Step-response model development for dynamic matrix control of a drum-type boiler–turbine system / Un-Chul Moon in IEEE transactions on energy conversion, Vol. 24 N° 2 (Juin 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N° 2 (Juin 2009) . - pp. 423 - 430 Titre : Step-response model development for dynamic matrix control of a drum-type boiler–turbine system Type de document : texte imprimé Auteurs : Un-Chul Moon, Auteur ; Lee, Kwang Y., Auteur Année de publication : 2009 Article en page(s) : pp. 423 - 430 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : MIMO  systems;  boilers;  nonlinear  control  systems;  predictive  control;  steam  turbines;  step  response Résumé : This paper presents the application of dynamic matrix control (DMC) to a drum-type boiler-turbine system. Two types of step-response models for DMC are investigated in designing the DMC; one is developed with the linearization of the nonlinear plant model and the other is developed with the process step-response data. Then, the control performances of the DMC based on both types of models are evaluated. Because of severe nonlinearity of drum water-level dynamics, it is observed that the simulation with the step-response model based on the test data shows satisfactory results, while the linearized model is not suitable for controller design of the drum-type boiler-turbine system.
