Application of Fuzzy Model Predictive Control in Multivariable Control of Distillation Column

Abstract

In this paper, a fuzzy model predictive control strategy is proposed for multivariable nonlinear control problem in a distillation column.This method is based on piecewise linear fuzzy model of the process to be controlled, which is used for predicting the outputs.An optimization technique is developed to minimize the difference between the model predictions and the desired prediction horizon.Comparisons are made with conventional controllers.The results confirmed the potentials of the proposed strategy of piecewise linear fuzzy control.
