Structure identification by means of density estimation in PM space

Popis výsledku v původním jazyce

We present the Preisach-Mayergoyz model (PM) of hysteresis phenomenon in nonlinear elastic spectroscopy. We explain the functionality of opening P_o and closing P_c pressures in the scalar Preisach triangular space for various types of hysteretic materials used in textile, electric or economic industry. We need to identify the two-dimensional probability density function in PM space, which is allowed to be represented by Gauss distribution or by the restricted power distribution with newly proposed optional parameters alpha, beta and under the maximal limit value chosen for the opening pressure. We illustrate this generalization and show how it is connected to the material structure which is to be estimated. One possible way of identification is to find the density function of P_o and P_c pressures by means of discretization of the Preisach's space. We developed and performed the software programme in Matlab which allows us to identify many various kinds of Preisach's densities in the
