Induction Motor Drive Parameters Identification Applying Difference Schemes

Abstract:

The authors have developed and tested by mathematical modeling the method of the induction motor parameters identification based on the difference schemes. When obtaining a difference equation system, the total delay time was taken to be equal to a quarter of a stator voltage period. The nonlinear predictive filtration was used to determine the expected value. The authors determined the estimators of rotor active resistance reduced to the stator; the rotor winding equivalent inductance; the stator winding equivalent inductance, the resulting inductance conditioned by the magnetic flux in the machine air gap; equivalent time constant for rotor circuit in the squirrel cage induction motor. The root mean square values of relative errors of parameters estimations total less than 4 %.
