Abstract

In this paper we discuss a simple yet realistic benchmark plant for evaluation and comparison of advanced multivariable control for chemical and biochemical processes. The benchmark plant is based on recycle-separator-recycle systems for ethylene glycol production and implemented in Matlab-Simulink platform. The benchmark plant is used to illustrate a procedure for plantwide control design in which Model Predictive Control (MPC) is evaluated and compared to a control structure based on single-input/single-output PID-controllers. We believe such a benchmark plant has a promising potential for education purposes (operator training, student education, etc) as well as scientific research into chemical process control where it enables rapid evaluation and comparison of advanced multivariable controllers as demonstrated in this study.
