Abstract

Per eseguire una regolazione automatica PID corrispondente ad uno stato di una macchina per stampaggio ad iniezione (M) in modo da eliminare una sovraelongazione (Po) o una sottoelongazione (Pu) di temperatura durante il termocontrollo di componenti termocontrollati della macchina per stampaggio ad iniezione (M), viene usata la teoria del "Fuzzy Control" (regolazione non lineare) per regolare la macchina per stampaggio a iniezione (M). Usando il sistema del Fuzzy Control, la temperatura oggetto dei componenti termocontrollati può essere raggiunta eliminando praticamente la sovraelongazione (Po) e la sottoelongazione (Pu).
