Integrated scheduling and control of a polymerization reactor with online closed-loop implementation

Yunfei Chu and Fengqi You,    Department of Chemical & Biological Engineering, Northwestern University, Evanston, IL 60208 USA

Abstract

Scheduling and control problems are traditionally solved sequentially. However, integration of both problems can result in a better overall performance. A main challenge in the integration is the solution to the derived mixed-integer dynamic optimization (MIDO) problem. To overcome the challenge, we present a novel integration method, which simultaneously determines the PI controller design and the scheduling decisions. The method decomposes the MIDO problem. The dynamic optimization for each transition can be ...
