Abstract

Process asymmetry often introduces severe difficulties to process modeling and worsens control system performance. In this work, a simple modeling framework is proposed, which can effectively tradeoff the difference between positive and negative process dynamics. It is characterized by small modeling effort in the consideration of process asymmetry. Modeling and control of a nonlinear high-purity ideal heat-integrated distillation column is conducted and the results obtained demonstrate the effectiveness of the modeling method proposed.
