        abstract = {This study investigates the closed-loop control of an induction motor drive using a multilevel inverter and constant V/f method. Multilevel inverters generate stepped sinusoidal voltages with lower harmonic content as the number of levels increases. A five-level inverter is developed using Sinusoidal Pulse Width Modulation (SPWM) for both the traditional VSI and cascaded MLI. The inverter output, having minimal THD, is filtered to improve the quality of the sine wave.The induction motor is modeled using a step-by-step mathematical approach after receiving this filtered voltage. The speed of the motor is controlled by maintaining a constant V/f ratio, and a PI controller is used to ensure that the motor speed follows the reference value. The closed-loop system is tested under different speed references and varying load conditions. A performance comparison is carried out between MLI and VSI-based induction motor drives, analyzing factors like transient response, steady-state behavior, efficiency, and cost. MATLAB/SIMULINK is used for simulation and result validation..},
