Abstract: The effects of the induction motors parameters on the stability of driving systems operating at variable frequency are analyzed in this paper with the help of conventional method using computer simulation. In this paper, Nyquist stability criterion method is presented. The poles and zeros of the transfer functions for the rotor speed are calculated to investigate the influences of the controller parameters and motor parameters. The drive system shows the instability of lower values of frequency. Stability of induction motor in vector control depends on parameter variation. Changes in stator and rotor resistances have an effect on stability analysis of vector controlled induction motor. The indirect vector controlled induction motor is modeled and simulated using MATLAB and various results have observed to check the effect on the stability of the drive for changes in the parameters offering the regions of stability
