It is known that the application of the field-oriented control strategy to induction motors needs the knowledge of the rotor flux components or the rotor resistance. The aim of this work is to show a method to estimate these quantities, based on the Kalman filter extended theory.

Abstract

It is known that the application of the field-oriented control strategy to induction motors needs the knowledge of the rotor flux components or the rotor resistance. The aim of this work is to show a method to estimate these quantities, based on the Kalman filter extended theory. The state equation of the Kalman filter results to be non linear because the rotor resistance is considered as variable. The observation equation contains the rotor flux components, which are derived from the integration of voltage signals, and the stator current ones. Simulation results obtained from this method show its effectiveness.
