Application of the internal model control method to a simulated dryer section of a paper mill

摘要

This paper presents an application of the Internal Model Controller (IMC) to the heat exchange in a dryer section of paper product industry. A quantitative discussion on numerical control of multivariable systems with use of reference-models is presented: the IMC design and application to multivariable systems are illustrated. The application of the IMC to a dryer section is studied, and some simulation test results are presented and discussed in the numerical control manner. The state model for the drying paper is based on the balance equations written for the steam, the paper, the wall of cylindrical heater, and the moisture. A methodology in developing the dynamic model is presented.
