Abstract

Per eliminare un eccesso (P?) od un difetto di temperatura (Pu) durante il termocontrollo di componenti termocontrollati, ad esempio un cilindro a iniezione (1), rispettando la temperatura voluta in ciascuno stato operativo della macchina di stampaggio di iniezione (M), viene utilizzata la teoria del "Fuzzy Control" per controllare la macchina di stampaggio a iniezione. Utilizzando il sistema del "Fuzzy Control" la temperatura voluta dei componenti termocontrollati può essere ottenuta eliminando praticamente del tutto l'eccesso (Po) e il difetto (Pu) di temperatura.
