ABSTRACT
Induction motors are extensively employed across various industrial applications, making efficient control strategies vital for improving performance, reducing operational costs, and enhancing system reliability. This study presents the implementation of a closed-loop Voltage-to-Frequency (V/f) control strategy for three-phase induction motor drives, with a focus on minimizing torque ripple and reducing input current harmonics. A systematic controller design is employed to iteratively fine-tune system parameters for improving dynamic response. Particular emphasis is placed on the reduction of input current harmonics and torque ripple—two critical factors influencing power quality and motor longevity. The performance of the designed controller is test by rigorous simulation. Simulation results demonstrate that the proposed approach reduces total harmonic distortion (THD) of the input current from 22.27% to 1.32%, and minimizes torque ripple from 1.50% to 1.08%. These improvements confirm that the proposed V/f control strategy, when combined with appropriate filtering, significantly enhances motor performance and stability under dynamic load conditions.
