State Space Realization of Wood Drying Process: Modeling, Simulation and Evaluation in Reality

The modeling of a wood drying process using a state space realization is considered. Based on balance equations for energy and mass in the air gap between the timbers, on the wood surface and within the wood, a state space realization consisting of linear and nonlinear parts is proposed which can describe the moisture content and temperature behavior of timber inside a drying kiln. Finally, the proposed state space realization is illustrated with a simulation and achieved results are evaluated by real measurements.
