VECTOR CONTROL SIMULATION OF INDUCTION MOTOR USING PI CONTROLLER

Sanjay J. Patel

Abstract :

This Paper is considered with the Vector control based speed control of an induction motor drive using P.I. controller. The vector control method has been optimized by using  PI controller. The orientation control of an induction motor has permitted fast transient response by decoupled torque and flux. The conventional PI controller has been widely used in industrial due to the simple control algorithm and easy implementation. The present controller combines the benefits of P.I. controller  and vector–control  in a single system controller. High quality of the regulation process is achieved through utilization of  P.I controller along with vector control method., while stability of the system during transient processes and a wide range of operation are assured through application of the vector–control. A PI controller of the motor speed is designed. With the help of Matlab/Simulink, block model of an induction motor drive is constructed and simulated. A superiority  PI controller in handling nonlinearity such as an induction motor has been effectively demonstrated by compå speed controller with conventional PI controller under varying operating conditions like step change in speed reference and torque reference. The result validates the robustness and effectiveness of the  vector control based speed control of 3–phase induction motor using P.I. controller.
