Development of a grey model for a medium density fibreboard dryer in ecosimpro

Abstract

[Abstract] This work contains the design and testing of a greybox model based on first principles for the drying section of a Medium Density Fiberboard (MDF) manufacturing plant for use in a Model-Predictive Controller (MPC).The fitting of the model to experimental data has been solved with the data reconciliation technique, and the model has then been implemented and tested in simulation for proper behavior. Due to lac k of information in a number of relevant process values, as well as low trustworthiness of some measurements,state and disturbance estimators have been determined as necessary to include in the final MPC control schema.
