Field-oriented control (FOC) was developed in the early 1970s and made it feasible to control the induction motor as a separately excited DC motor (Barambones and Alkorta, 2011). Field-oriented control can be classified as indirect field-oriented (IFO) and direct field-oriented (DFO) control. Both of these approaches provide torque control of the induction motor by decoupling the torque and flux (Nounou and Rehman, 2007). There are different ways of implementing the vector control strategy according to the choice of the reference frames for the space vectors. In an induction motor, there are three distinct flux space phasor: air gap flux, stator flux and rotor flux.
