2008 (English)In: 2008 IEEE International Symposium on Computer-Aided Control System Design: [CACSD] ; San Antonio, TX, 3 - 5 September 2008, Piscataway, NJ: IEEE Communications Society, 2008, 365-370 p.Conference paper (Refereed)
This paper deals with DRGA analysis for uncertain systems. Uncertainties in a process model can be translated into uncertainties in the DRGA which might invalidate the decision on the variable paring in decentralized control. Bounds for the uncertainties in the DRGA of a multivariable process are derived for a given nominal process model with known uncertainty region. The resulting uncertainty region for the DRGA is used to assess the validity of decisions based on the nominal DRGA. The methodology for the computation of the bounds is currently restricted to the 2-by-2 case. Beside an explanatory example, a case study on a coal injection vessel is conducted and discussed.
