Application of Butterworth filter for parameter identification of an induction machine

Abstract

The authors present the application of Butterworth filter for parameter identification of an induction machine. MlMO (multi-inputs/multi-outputs), SISO (Single-input/Single-output) and MISO (multi-input/single output) continuous model structures were undertaken by using the recursive least square algorithms. The identification of the induction machine parameters is carried out from the experimental standstill tests where an electric request without danger to the windings, is supplied by a DC-chopper, giving a capacity of persistent excitation which has for effect to generate a signal rich with information.
