Multivariable Control of A 4x4 Process in Distillation Column

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A model predictive control strategy is proposed for multivariable nonlinear control problem in a 4x4
process in distillation column. The aim is to provide a solution to nonlinear control problem that is
favorable in terms of industrial implementation. The scheme utilizes multiple linear models to cover wider
range of operating conditions. Depending on the operating conditions, suitable model is used in control
computations. Servo and regulatory controls of the system are examined on constrained and
unconstrained conditions. Comparisons are made to conventional controllers. The results confirmed the
potentials of the proposed strategy.
