MODAL ANALYSIS AND SECONDARY MEASUREMENT SELECTION FOR THE CONTROLLER DESIGN OF HEAT INTEGRATED DISTILLATION COLUMNS.

Abstract

The control problem of two distillation columns with heat integration has been analyzed in the present work and laternative control structures have been synthesized. A modal analysis was performed and the dominant dynamic characteristics of the integrated system were revealed. The alternative sets of manipulated variables were selected as the approximate closely the model matrix of the linearized system. Due to the fact that not all states are measurable, alternative sets of composition measurements have constructed within the framework of the modal analysis. The dynamics of the generated closed-loop configurations have been examined numerically for optimized gain matrices. Numerical results indicate that this alternative approach is superior to the linear static estimator and offers potential for future expansion.
