New flux weakening control for high saliency interior permanent magnet synchronous machine without any tables

Abstract

This paper presents a new flux weakening algorithm for high saliency Interior Permanent Magnet Synchronous Machine. The proposed method modifies the current reference not by look-up tables, but by a controller in order to achieve a flux weakening. The current reference modification is determined by the d-q axis current and output voltage using the gradient… (More)
