Abstract

Die Erfindung betrifft ein Verfahren zur Regelung der Temperatur einer Glühkerze (1), wobei aus einer Solltemperatur (TSolll) ein Sollwert (Rsoll) einer temperaturabhängigen elektrischen Größe ermittelt wird, und eine durch Pulsweitenmodulation erzeugte Effektivspannung (Ueff) an die Glühkerze (1) angelegt und als Stellgröße verwendet wird. Erfindungsgemäß ist vorgesehen, dass mit einem mathematischen Modell (4) ein erwarteter Wert (Re) der elektrischen Größe berechnet wird, die elektrische Größe gemessen wird, durch Auswertung des berechneten Wertes (Re) ein erstes Fehlersignal e1(t) erzeugt wird, als Eingangsgröße des mathematischen Modells (4) ein aus dem Wert der Effektivspannung (Ueff) und dem Fehlersignal (e1(t)) berechneter Wert verwendet wird, wobei das mathematische Modell (4) aus der Eingangsgröße eine Ausgangsgröße (X) berechnet, die den erwarteten Wert (Re) der elektrischen Größe vorgibt, mit der Ausgangsgröße (X) des mathematischen Modells (4) ein korrigierter Wert für die Effektivspannung (Ueff) berechnet und die Effektivspannung (Ueff) auf den korrigierten Wert geändert wird.

The invention relates to a method for regulating the temperature of a glow plug (1), wherein a nominal value (R soll ) of a temperature-dependent electrical variable is determined from a nominal temperature (T Solll ), and an effective voltage (U eff ) generated by pulse width modulation to the glow plug ( 1) is created and used as a manipulated variable. According to the invention, an expected value (R e ) of the electrical variable is calculated with a mathematical model (4), the electric variable is measured, and a first error signal e 1 (t) is generated by evaluating the calculated value (R e ) , an input value of the mathematical model (4) is a value calculated from the value of the effective voltage (U eff ) and the error signal (e 1 (t)), the mathematical model (4) calculating an output quantity (X) from the input variable which predetermines the expected value (R e ) of the electrical quantity, uses the output quantity (X) of the mathematical model (4) to calculate a corrected value for the effective voltage (U eff ), and changes the effective voltage (U eff ) to the corrected value ,
