Abstract

En posisjonsstyrekrets (70) har en demodulator (22) med automatisk avstemningsmulighet for bruk i et elektro- hydraullsk posisjoneringssystem som anvendes til å posisjonere en servoanordning (40). Posisjonsstyrekret- sen innbefatter demodulatoren (22), en analog/digital- omformer (28) med et inngangsspenningsområde, og en mlkrostyreenhet (26). Demodulatoren har en forsterkning og er virksom til å omforme et tllbakekoblet signal fra servoanordningen til et posisjonssignal som har en nedre spenningsverdl når servoanordningen er på sin Oi posisjon og en øvre spenningsverdi når servoanordningen er på sin 100£ posisjon, idet den nedre spennlngverdien og den øvre spenningsverdien er en funksjon av demodulatorforsterkningen. Ved operatørinitiering vil mikrostyreenheten (26) automatisk beregne den største verdi for demodulatorforsterkningen som resulterer i at posisjonssignalet fra demodulatoren (22) har en nedre spenningsverdl innenfor et nedre spenningsområde og en øvre spenningsverdi Innenfor et øvre spenningsområde, der det nedre spenningsområdet og det øvre spenningsom- rådet er Innenfor inngangsspenningsområdet for nevnte analog/digitalomformer (28).
