Vector control of induction motors has achieved a quick torque response. It is very
sensitive to flux estimation (magnitude and orientation). The flux estimation is affected by
parameters variation. These parameters are affecting saturation, temperature, and skin effect. The
mismatching between the parameters value used in the controller and those in the motor make the
actual rotor flux position does not coincide with the position assumed by the controller. Any
parameter mismatched in flux estimation will be detrimentally affect the torque response and then on
the dynamic performance. So this paper shows the effect of mismatching in rotor reactance between
the control model and the machine itself on the performance characteristics of induction motor
through applying the vector control. The rotor reactance is chosen due to have more effect on the
instantaneous slip speed. To show this effect, the mismatching case is compared to matching case
and with scalar control. MATLAB program is used to simulate these cases.
