Structural and parametrical synthesis of cybernetic model of elastic ionic polarization

Abstract

This article deals with modification of cybernetic description of elastic ionic polarization process of biatomic crystal. Definite structural modifications were conducted to reduce the computational error of polarization characteristics calculation. The modified model helped to develop the algorithm of effective parametric synthesis of crystal parameters and dynamic parameters of the process using numerical multidimensional optimization methods. The proposed measures will improve the accuracy of the simulation results of the polarization characteristics for dielectrics, which has become evident due to series of numerical experiments. Also parametric synthesis algorithm, made with the use of modified cybernetic model, allows us to calculate the value of previously unknown crystal compressibility factor taking into account sufficiently detailed polarization spectra.
