Fast Preisach Based Magnetostriction Model for Highly Magnetostrictive Materials



Edward Della Torre


A Preisach based magnetization model is presented to work specifically on highly magnetostrictive materials. The model accounts for the additional anisotropy introduced when a prestress is used to activate the high strain, by using a bimodal structure. The necessity of strain feedback to deal with the magneto-mechanical effect is discussed and found to be unnecessary for these types of material. The model is based on a fast implementation of the DOK model so it is suitable for real time control applications.
