Abstract-This paper presents a comprehensive study of scalar and vector control techniques for three-phase induction motors fed by inverter topologies. Scalar control, commonly known as Voltage/Frequency (V/f) control, offers a simple, cost-effective method for motor control but is limited in its precision, torque regulation, and dynamic response. In contrast, vector control (or field-oriented control) decouples the motor’s torque and flux components, providing enhanced performance, including faster response times, improved speed and torque accuracy, and reduced harmonic distortion. MATLAB/Simulink simulations are used to evaluate both methods under various load and speed conditions, demonstrating the superior dynamic performance, accuracy, and reduced harmonic content of vector control, making it ideal for high-performance industrial applications.
