Abstract :
The purpose of this paper is to give a state model for drying paper. This model is based on the balance equations written for the steam, the paper, the wall of cylindrical heater, and the moisture. Thus, the balance equations gives a set of six nonlinear partial derivative equations. The form of these equations changes somewhat from one cylindrical heater to other. Its solution yields the operating parameters need to realize the desired steam temperature with a good drying of the paper. Boundary conditions are specified by a stochastic generator. Initial conditions are obtained by solving the static model. In this paper we present only the state model for drying paper and compare the obtained results with the dynamic model results. Solving the set of differential equations with respect to the boundary conditions, we obtain a standard form of the state representation which represents the dynamic version of the model used for control
