Abstract

This paper reports the experimental results of a predictive controller applied to a pH neutralization plant. A pretest was used to get an approximate transfer function (first order plus dead time) to tune a PI controller, in order to collect data in closed-loop. The process was then identified in closed-loop with the PI controller to get linear models and the best models were chosen to implement the predictive controller. The performance of the predictive and the PI controllers was compared.
