Modifications that are necessary in the structures of rotor flux computers and indirect vector controllers in order to take into account the main flux saturation are considered. The schemes discussed are based on measurement of the main flux and stator currents, stator voltages and stator currents, and stator currents and rotor speed. Particular attention is given to a calculator based on stator currents and rotor speed as measured variables and to simplified saturated indirect vector controllers. Verification of the proposed saturated rotor flux calculators and indirect vector controllers is provided by means of digital simulation. One of the schemes is applied in a vector-controlled induction motor drive, and experimental results are included.<>
