摘要: Abstract The paper presents an attempt to estimate the parameters of Jiles–Atherton description magnetization process. approach relies on direct search solution space in order minimize error between measured and modelled hysteresis curves for quasi-static conditions. obtained model are then used predict dynamic loops. proposed algorithm is able omit local energy minima. effect eddy currents considered by introduction additional component field into equation. validity has been proved loops a nanocrystalline material Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 .
