Energy-aware black box MIMO model identification of wood chips refining process operating in closed loop

The presentation will deal with the identification of a reduced black box LTI MIMO model of a wood chip refining process operating in closed loop. The specific fiber extraction process is dedicated to the production of Medium- density Fiberboard (MDF). The model is designed to predict the behavior of the two main quantities from the energy consumption perspective: the motor current of the refiner and the motor current of the plug screw. In the next steps, the obtained model will be employed for the economic multi- objective optimization of the process, which aims at minimizing energy consumption, maximizing the fiber quality, and ensuring compliance with the production constraint. This research activity is carried out within the EU project E2COMATION, Life-cycle optimization of industrial energy efficiency.
