Sažetak
The mathematical model of flux-current hysteresis of the magnetic circuit is presented in the paper. The flux-current characteristic is modeled by the analytic function consider the hysteresis phenomena. The flux-current hysteresis is approximated by a linear combination of a number of the Gompertz functions and linear function. The parameters of the analytic function are determined using the measured flux-current data. The proposed method is performed trough two steps. The first step is an estima-tion of the analytic function parameters by the evolutionary algo-rithm and the second is approximating of the hysteresis by the analytic function. The use of the flux- current hysteresis model is presented by the simulation of the magnetization current at speci-fied voltage in OpenModelica software. The simulated currents are compared with the measured ones.
