چکیده :
it is worth noting that the possibility of using any control method increases the opportunity to reduce losses in electrical machines and inverters, which leads to a clear increase in efficiency and reduction of electrical losses. Therefore, it is important in any electrical system, especially the electric machines used in electric cars, to choose the ideal control method, as field oriented control or vector control theory is the latest method in electrical control, and it has attracted and received the attention of researchers and scientists in many industrial fields. In this research, a control system was developed using the field oriented control field oriented control method to control electrical machines. All electrical losses in the electrical machine were studied and analyzed (Cupper losses, iron losses resulting from eddy currents, mechanical losses resulting from friction). The losses in the inverter were also analyzed and studied, as most of they did not discuss it, as it plays an important role in the possibility of increasing or decreasing the efficiency of the system. Finally, the method field oriented control by losses minimizing control LMC results were simulated, and the results include current, modulation index, switching frequency, and all variables in the drive system. Furthermore, the maximum efficiency control strategy was chosen so that the drive system can operate in the most efficient conditions at all operating points. The driving efficiency can be improved by reducing the inverter and PMSM losses, as the comparison was made by the proposed method and the classical field oriented control method.
