Identification of magnetic characteristics of induction motors based on the Jiles-Atherton model

Abstract

Precise estimation of flux and accurate modeling are of paramount importance for improving control performance in induction machines. Non-linearities limit the performance of control techniques, which in general assume linearity of the components. The paper proposes a procedure to identify magnetic saturation and hysteresis losses, which uses the available current and voltage measurements from the inverter and is based on the Jiles-Atherton theory. The theoretical achievements are tested on an experimental test rig, showing practical feasibility of the method.
