Model algorithmic control for paper machines

Abstract

Paper-making processes are multivariable systems with long time delay. Model algorithmic control (MAC) strategy, which is based on impulse response model, is very suitable for such kind of processes. It has the advantages that the impulse response models are easy to obtain, and the control system is robust to model errors and process disturbances. This paper investigates the application of model algorithmic control in paper machines. Feedforward decoupling is employed to eliminate the coupling in the process. Open loop system identification algorithm is applied to obtain process model. Simulation studies have been conducted on a real world paper machine. The results have indicated the satisfactory performance of basis weight and moisture content control using MAC strategy.<>
