A Simple Method for Modeling Process Asymmetry
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 trade-off 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.
