(2011)Magnetics, IEEE International conference, Proceedings. Mark abstract The magnetic properties of the magnetic circuit of an electromagnetic device (EMD) can be identified by solving an inverse problem, where sets of measurements are properly interpreted using a forward numerical model of the device. However, the uncertainties of the geometrical parameter values in the forward model result in recovery errors in the reconstructed material parameter values. This paper proposes a novel inverse approach technique, in which the propagations of the uncertainties in the model are limited. The proposed methodology adapts the cost function that needs to be minimized with respect to the uncertain geometrical model parameters. We applied the methodology onto the identification of the magnetizing B-H curve of a switched reluctance motor (SRM) core material. The numerical results show a significant reduction of the recovery errors in the identified magnetic material parameter values.
