SCREENING TOOLS FOR ROBUST-CONTROL STRUCTURE SELECTION

Abstract

Screening tools for control structure selection in the presence of model/plant mismatch are developed in the context of the Structured Singular Value (mu) Theory. The developed screening tools are designed to aid engineers in the elimination of undesirable control structure candidates for which a robustly performing controller does not exist. The screening tools are examined on a multi-component distillation column control problem and compared with previously published methods such as the Condition Number Criterion.
