Abstract
L'invenzione si riferisce ad un metodo per determinare il flusso di statore di una macchina asincrona quando vengono misurate una corrente di statore (SIMBOLO) ed una tensione di statore (SIMBOLO) della macchina asincrona e si assume che siano note un'induttanza di cortocircuito (?Ls), un'induttanza di statore (Ls) ed una costante di tempo del rotore (Tr) della macchina, in cui viene determinato il prodotto della corrente di statore (Ts) e di una stima della resistenza di statore (Rse), il prodotto ottenuto viene sottratto dalla tensione di statore (SIMBOLO), e la differenza di tensione ottenuta viene integrata rispetto al tempo per ottenere una prima stima del flusso di statore (SIMBOLO). Nell'invenzione, il metodo inoltre comprende i passi di determinare una seconda stima del flusso di statore (SIMBOLO) sulla base della tensione di statore (SIMBOLO), della corrente di statore (SIMBOLO) dell'impedenza di cortocircuito (?Ls), dell'induttanza di statore (Ls), della costante di tempo del rotore (Tr) e della stima della resistenza dello statore (Rse); determinare un termine di correzione del flusso (SIMBOLO) come differenza tra la prima stima del flusso di statore (SIMBOLO) e la seconda stima del flusso di statore (SIMBOLO), e sommare il termine di correzione del flusso (SIMBOLO) pesato per mezzo di un coefficiente costante (w) con detta differenza di tensione.(fig.5)
