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 estimation of the analytic function parameters by the evolutionary algorithm 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 specified voltage in OpenModelica software. The simulated currents are compared with the measured ones.
