COMPARISON OF MODEL-BASED AND CONVENTIONAL CONTROL - A SUMMARY OF EXPERIMENTAL RESULTS

Nonlinear and linear model-based control(MBC) strategies including pro cess model-based control (PMBC), model predictive control (MPC), inter nal model control (IMC), and advanced conventional control (ACC) have been experimentally compared for flow, temperature, pressure, and comp osition control. The test systems have nonlinear characteristics and i nclude a pilot scale fluid flow and heat exchanger system, a commercia l plasma reactor, and a laboratory scale distillation column. The eval uation criteria includes the effort required for model development and implementation, as well as conventional measures of controlled and ma nipulated variable activity.
