| Abstract: | The paper presents an optimal control strategy selection for an induction motor during voltage start-up, focusing on limiting the maximum current and starting torque surges at a given start-up time. Optimizing the operation of a soft-start system can be achieved using a simple system that assumes a linear voltage increase from a specific initial value. The advantage of this approach is the elimination of transducer systems for measuring voltages and currents. That approach requires simulating the drive system to select the optimal variant for a given system based on maximum and minimum torque values, maximum current, and optimal starting time. Transient calculations, for example, for the induction motor, were performed using both the analytical and circuit-field methods for different U/f time characteristics under varying motor load conditions, and the simulation results were compared with measurements.
