Formel: Y = PID (Sollwert.zu, Zulufttemp, TA, P, I, D) Heiz und Kühlsequenz Die Stellgröße Y wird auf die Bereiche 0100% skaliert und steuert das Heizventil und das Kühlventil an. Formel: Heizventil = y (5 + (Neutralzone / 2) * 100 / (5 (Neutralzone / 2)) Heizpumpe = ein * heizventil > 1 // Pumpe EIN, wenn Ventil > 1% Kuehlventil = y (5 (Neutralzone / 2) * 100 / ((Neutralzone / 2) 5) Kuehlpumpe = ein * kuehlventil > 1 // Pumpe EIN, wenn Ventil > 1% 100 % //Variable: neu ta neu y neu p neu i neu Sollwert.zu neu Raumsollwert //Zuweisungen: // Abtastzeit // Stellgrösse (Rechengrösse) // Proportionalfaktor // Nachstellzeit // errechneter Zuluftsollwert // Hauptsollwert ta=5 // in Sekunden p=1 // Proportionalfaktor i=120 // in Sekunden Raumsollwert=20 // in Grad Celsius //Programm: A1 A9 A2 A10 E2 E1 RCO 0 % Neutralzone Zulufttemp lo pr zu_ab_kaskade neu pr zu_ab_kaskade ae zu_ab_kaskade Beschreibung: Ergänzungen zur dargestellten Regelung sind in weiteren Applikationen aufgeführt. Kaskadenregelung Der Hauptregler ermittelt mittels PVerhalten die Führungsgröße (Sollwert.zu) für den mit Zuluftbegrenzung Hilfsregler aus der Regeldifferenz zwischen Raumsollwert und Ablufttemperatur.
