Integration of design and control through model analysis

A systematic analysis of the process model is proposed as a pre-solution st ep for integration of design and control problems. It is shown that the sam e set of process (control) variables and design (manipulative) variables is employed with different objectives in design and control. Analysis of the phenomena models representing the process model identify the relationships between the important process and design variables, which help to understan d, define and address some of the issues related to integration of design a nd control issues. The model analysis is highlighted through examples invol ving processes with mass and/or energy recycle. (C) 2000 Elsevier Science L td. All rights reserved.
