Device and computer-implemented method for controlling an extrusion plant, extrusion plant, and computer-readable storage medium

An apparatus for controlling an extrusion installation having at least one extrusion head for shaping at least one extrudate, the apparatus comprising:

• a profile determining unit configured to determine a warm extrudate profile of at least one extrudate, wherein the warm extrudate profile defines geometric data of the extrudate in a warm state;
• a first cold-profile modeling unit configured, on the basis of the warm extrudate profile and initial process parameters, to parameterize an extrudate model which determines a first cold extrudate profile of the extrudate in a cooled state;
• a comparison unit configured to determine a first deviation between the determined first cold extrudate profile and a specified extrudate profile,
• a parameter determining unit configured, using the first deviation, to optimize process parameters and to determine changed process parameters, such that a deviation of a cold extrudate profile that is produced from the specified extrudate profile is less than two percent;
• a selection unit configured to select the changed process parameters as the input for the activation unit if the deviation is less than or equal to a threshold value, and
• an actuating unit configured to control the extrusion installation with the changed process parameters, in particular in order to produce a second warm extrudate.
