Research on optimization of vector control of an asynchronous motor using the analytical control system

THE PURPOSE. The rapid development of electric transport requires the use an energy-efficient drive in order to increase range runs between battery charges. This, turn, research optimize system based on asynchronous motor with a combined winding. METHODS.. A combination winding is high performance stator consisting two star and delta windings connected parallel. structure mathematical model engine, which are basis for constructing engine control algorithm, considered. algorithm determining optimal value magnetic flux coordinates d - q axis achieve low power losses, taking into account losses iron core saturations, helps improve efficiency inverter control. RESULTS. pre-tested several simulations then experimentally verified by applying proposed technique 1.5 kW controlled field induction (FOC) drive. CONCLUSION. obtained results presented discussed, demonstrating that online can significantly reduce loss
