MODELING SIMULATION AND CONTROL OF THE WOOD DRYING PROCESS - PART 1 -A SET OF PDES AS AN INTERNAL MODEL

The internal model proposed is a nonlinear system of a few partial dif ferential equations. The boundary conditions for the differential equa tions are specified at the lumber board entrance and between the wood and air. The initial conditions are calibrated by solving the static m odel and by the technical experiment. In conclusion, it can be said th at the consistency of the model with experimental results seems to be reasonably good and can be used for process simulation and control.
