Control of AC induction machines using the vector control techniques is becoming more popular nowadays. The need for extensive computations has no more become an objection to the vector control implementation. This is due to the wide availability of high speed digital processors.. The objective of vector control of induction machine is to allow an induction machine to be controlled just like a separately excited dc machine. When the dynamic equations for an induction machine is transformed by means of rotating transformation methods into a reference frame that coincides with rotor flux, the results become similar to that of a DC machine. This allows AC machine to be controlled just like a DC machine.
