In Fig. 3 is shown our proposed IFOC scheme. Two of the main units of the classical IFOC are replaced by our
proposed fuzzy control system. The replaced units are: the unit which estimates the motor’s rotor flux, φ, based on
motor model and the unit which uses the rotor flux reference, φ*r, to compute the stator current direct
component i*required to produce the rotor flux in the motor.
