ABSTRACT
Here, main purpose of the indirect field oriented control strategy is to decouple the torque and flux vectors in synchronous rotating frame of induction machine, through which we can achieve an independent speed and torque control and good dynamic response. This indirect field oriented control (Now onwards called as IFOC) scheme will also improve the drive performance. Hysteresis current control technique is used here for closed loop control of inverter because of its simplicity of implementation and quick response. PI controller is tuned by trial and error method here, and is used for speed control so that it will track an exact speed given as a reference input and generates torque command accordingly. Due to the several features of this drive it is very useful in industries and now a days they are replacing traditional scalar controlled drive. Simulation results are discussed here and obtained using MATLAB/SIMULINK package.
