ESTIMATION DES CONSTANTES DE TEMPS STATORIQUE ET ROTORIQUE DE LA MAS

Abstract

This work involves real-time estimation of the stator and rotor constants of the three-phase asynchronous machine (MAS). The work is based on the application of the Extented Kalman Filter for estimating state variables and its parameters. First of all, the MAS is modeled in the reference linked to the stator by highlighting the stator and rotor constants. Then the FKE algorithme is applied. Simulation under Matlab/Simulink tests the validity of the approach used. A real-time implementation on a space ma pis realized. Finally, the experimental measurements made it possible to compare the simulation and experimental results
