us, calculation of the rotor ux position requires only measurement of the rotor position. However,
stator current measurement is still necessary for the CC of the power supply.
RFOC scheme in which the rotor ux position is obtained by means of (24.37) and (24.38) is known
as indirect rotor ux oriented control (IRFOC) scheme. ...
