V/F Control of Three Phase Induction Motor

Control of induction motor (IM) is more important because most of the industry used the induction motor, and control in the cost of decrease the efficiency and performance of the machine. For controlling the induction motor main aim to maintain the efficiency and performance of the machine. Pi controller is used for describing the V/F control of induction motor in this paper. Reduction in the error between rotor speed and reference speed is done using the PI controller. Using this PI controller, we change in frequency of the voltage source inverter (VSI) to maintain the V/F ratio is constant. After we try to do some modification in pi controller and take reference of PI and try to minimize error and improve the performance and harmonics elimination of the induction motor.
