On-line Electrical Parameters Estimation of an Induction Motor

The article presents a new method for on-line estimating the electrical parameters of an induction motor. In this regard, a Luenberger observer is used, which is online adapted according to the estimated electrical parameters. The stator and rotor resistance, stator inductance as well as dispersion coefficient are estimated based on some adaptive methods. The estimation method is tested and validated by simulation in Matlab-Simulink.
