The aim of the study is to expand the capabilities offered by dynamic simulation of electrical drive control systems to adjust their operation under electrical machine core saturation conditions. The article describes an electrical machine modeling method that combines analytical calculation and finite element analysis. The functionality of the obtained model allows it to be used as part of a control object in a dynamic simulation system. Supplementing the analytical model with the finite element method allows one to accurately take into account all features of the machine magnetic system geometry and nonuniform saturation of the cores. The practical implementation of the proposed model using the Octave and FEMM software packages, and its interaction with the SimInTech dynamic simulation environment are considered. In particular, the interaction structure and features of specifying the material magnetization curve and calculating the differential inductances of the electrical machine windings using the finite element method are described. The results from experimental tests of the model for simulating electromagnetic transients in a system with negative current feedback are given. The proposed structure can be used as a basis for constructing models of various electrical machines suitable for use in a dynamic simulation system to test the control system performance under core saturation conditions and for any rotor displacements.
