Abstract :
In this paper speed control of an Induction Motor using Indirect Field Oriented Control (IFOC) method has been developed and simulated. In this work the complete mathematical model of field oriented controlled Induction Motor is described and simulated in MATLAB/SIMULINK. For studies a 200 HP(150kw ) squirrel cage type IM has been considered. The comparative study of IFOC and conventional V/f control of IM is done in this work. The IFOC induction motor drive involves decoupling of the stator current components which produces torque and flux. It is seen that it provides smooth speed control, can generate full torque at zero speed and capable of fast acceleration and deceleration compared to V/f control.
