Abstract
A method able to generalize the static Preisach hysteresis model for dynamic loops under sinusoidal time-varying fields is presented in this paper. The aim is to obtain an equivalent static model for dynamic loops. Then, the Preisach distribution function parameters are updated according to the frequency of the excitation magnetic field. The frequency-dependent parameters have been evaluated by genetic algorithms. Validations based on a comparison of the results of the present approach have been made with a different classical numerical approach modeling dynamic loops.
