1. Introduction
Induction motors are widely used in various industrial applications due to
their robustness, reliability, and cost-effectiveness. However,
controlling the speed of an induction motor is challenging, as it requires
precise control of voltage and frequency. VF control technique provides an
effective solution to achieve variable speed control in induction motors.
2. VF Control Principle
VF control principle is based on the fact that the electromagnetic torque
produced by an induction motor is proportional to the square of the
voltage-to-frequency (V/F) ratio. By varying the voltage and frequency
supplied to the motor, the speed of the motor can be controlled. This
section explains the mathematical model and control strategy employed in
the VF control technique.
