Refiner control This section concentrates on the control of chip refining and thermomechanical pulping (TMP). It opens different views to modelling and control of plate refiners that are nowadays the most important machines in the chip refining area. In spite of measurement difficulties, they are highly automated processes because of quality reasons and the remarkable
