Controlling complex chaotic systems and analyzing their behavior have emerged as an attractive field of exploration in different domains of engineering. Over the years, large number of mathematical tools are developed to identify and control the typical behaviour of these systems. The work presented in this manuscript explores chaos in nonlinear dynamics of an indirect field controlled induction motor drive system. For this exploration, impact of variation in rotor inductance is considered while assuming the load torque to be fixed. Chaotic attractors are first verified by investigating Lyapunov Exponents. The range of parametric variation is explored to check for the events where chaos can creep into the system again. Finally, an attempt is made to measure the transition point between stability and instability of the chaotic system. This is verified using the Lyapunov Exponent measure and the phase plots. The detailed simulation results highlight the efficacy of the methodology to identify the chaotic behaviour of the induction motor.
