Tuning PCA controllers based on manual control data

In this paper an approach for tuning PCA controllers based on manual control data is presented. Closed-loop control can be formulated and implemented within the reduced space defined by a PCA (principal components analysis) model. This PCA controller results in an integral controller. The main contributions of the paper are: a) the tuning approach based on process data obtained with a manual closed loop controller, and on the adjustment of the controller gain; b) the performance evaluation of this new approach, in nominal operating conditions and in faulty situations. Some experimental results obtained with a second order linear plant are presented.
