Abstract

Electric machines are one of the most important pieces of equipment in modern industrial processes. However, due to different applications and for energy efficiency, most of the electric machines are not directly connected to the power grid, but through a power converter. This allows to control the speed, torque, and therefore the currents and voltages, increasing the number of applications for higher power processing. This study compares three control strategies for induction motors: Indirect Field Oriented Control (IFOC), Direct Torque Control (DTC), and Predictive Torque Control (PTC). Their performance is evaluated in terms of efficiency, steady-state and transient response. Simulation results indicate that IFOC achieves the lowest total harmonic distortion (THD), while PTC shows promise as an alternative for power electronics applications. The results provided in this investigation demonstrate the advantages and disadvantages of the techniques proposed above.
