Abstract

Die Erfindung betrifft eine modellbasierte Regelung einer Heizstrecke, wobei in der Heizstrecke ein Material durch ein radial geschlossenes Gehäuse bewegt wird, wobei je Heizzone (12) der Heizstrecke ein Heizelement (6) und ein unterlagerter Regelkreis vorhanden sind, dessen Heizzonenregler (13) eine Heizelementtemperatur der jeweiligen Heizzone regelt, wobei Messwerte von Temperatursensoren (14, 15) an einen Smartsensor (8) übergeben werden, wobei der Smartsensor (8), basierend auf den Temperaturmesswerten (14, 15), thermische Istzustände schätzt, wobei der Smartsensor (8) diese geschätzten Istzustände an eine modellprädiktive Regelung (7) liefert, wobei die modellprädiktive Regelung (7) einen Sollwertverlauf für eine Zonentemperatur vorgegeben bekommt, wobei die modellprädiktive Regelung (7) aufgrund der geschätzten Istzustände und eines hinterlegten mathematischen Modells jeweils einen Verlauf von Sollwerten der Heizelementtemperatur je Heizzone (12) berechnet und den aktuellen Wert dem jeweiligen Regelkreis der Heizzone (12) vorgibt, um eine vorgegebene Zonentemperatur zu erreichen.
