Abstract
U radu je izvršena estimacija parametara nelinearne zavojnice s pomoću metode najmanjih kvadrata. Nelinearna zavojnica modelira se s pomoću nelinearnog induktiviteta i nelinearnog otpora (linearni po odsječcima). Prikazane su karakteristike dobivene estimacijom pri stalnoj frekvenciji i povećanju napona. Na temelju prikazanih karakteristika dolazi se do zaključka, da je podudaranje histereza jako dobro. Povećanjem napona dolazi do povećanja struje, a time se povećavaju rezidue. Najveći utjecaj u doprinosu struje zavojnice ima struja induktiviteta

Parallel abstract (English)
In this paper, an estimation of nonlinear coil parameters was performed by using the least squares method. The nonlinear coil is modeled by nonlinear inductance and nonlinear resistance (piece-wise-linear characteristics). Characteristics obtained by estimation at constant frequency and voltage increase are shown. The conclusion is, based on the displayed characteristics, that hysteresis matching is quite good. By increasing the voltage, the current increases as well as the residuals. The greatest influence on the coil current contribution has the inductance current
