Features of Linear Models that May Compromise Model-Based, Plant-Wide Control Techniques: The Case of the Tennessee Eastman Plant

Abstract

This work examines a set of features that impact the reliability of linearmodels within the context of plant-wide control design (PWC). The study case isthe Tennessee-Eastman (TE) plant. This benchmark problem is well-known forchallenging many control design approaches. Analyses involve eigenvalues,average errors between simulations, condition numbers, and loss of rank acrossfrequencies. These studies offer guidance for designing an effective plant-widecontrol system based on linear models.
