Abstract: In recent years a number of studies have been carried out in relation to improvements in control methodologies for induction motors, and due to the great progress achieved in power electronics and microcontrollers, it has been possible to implement advanced Control for this type of electric motors. The purpose of this paper is to achieve the implementation of an advanced control technique, such as vector control for induction motors. Specifically, the methodology is Indirect Field Oriented Control (IFOC) based on the space vector pulse width modulation necessary for the control of the inverter that feeds the motor. The main characteristic of the vector control is that it allows direct control of the stator current according to the desired requirements and improving its efficiency. In this paper project the analysis and the implementation of indirect field oriented control (IFOC) for a three-phase induction motor. This control algorithm makes use of Two PI controllers are available for the currents, and another PI controller for the speed, which together make motor control possible. The main objective of the control is to follow a speed reference and maintain it in spite of the presence of disturbances. In addition, relationship between the reference speed and the reference current, in order to achieve control over a wider range of speeds. The software used to perform the simulations in this paper is MATLAB/ Simulink are used to perform the simulations of the mathematical model and the control algorithm .the components used are presented and the results obtained which shows the behaviour of the currents at different speed levels are high response.

Keywords: indirect field oriented control, PI controllers, space vector pulse width modulation.
