Modeling, Calibration and Control of a Paper Machine Dryer Section

In English Following increased efforts during the last decade to
formulate mathematical models for the paper drying
process, this paper presents a Modelica library,
DryLib, which enables users to rapidly develop complex
models of paper machine dryer sections. In addition,
parameter optimization, model reduction and
moisture control by means of Non-Linear Model Predictive
Control is treated. These applications have in
common that they are based on numerical optimization
schemes. Since the nature of the particular optimization
problem dictates the requirements of the numerical
code, the paper also serves as an illustration of the
need for flexibility in terms of i) means for the user to
express optimization problems, ii) and choice of numerical
algorithms.
