In this paper, an improved scheme of adaptive flux observer of induction motor is proposed. This adaptive observer is used with fieldoriented control of induction machine. It is based on using induction motor model with the estimation of the load torque besides the estimation of the rotor resistance. The robustness of this observer with respect to the variation of the rotor resistance, known to be a crucial parameter for the control, is studied. The performances of the proposed adaptive observer were compared to those of the classical one via numerical simulation. The obtained results show the effectiveness of the proposed scheme.

Przedstawiono ulepszoną metodę adaptacyjnego obserwatora strumienia w silniku indukcyjnym. Bazuje ona na modelu silnika indukcyjnego przy określeniu momentu obciążenia. Odporność obserwatora względem zmian rezystancji wirnika jest jednym z ważniejszych parametrów. Porównano parametry proponowanego obserwatora z metodami klasycznymi przy wykorzystaniu numerycznej symulacji. Otrzymane rezultaty potwierdziły skuteczność nowej metody.
