The present paper focuses on the inner product of current and flux referred MRAS for evaluating the value of the time constant. The steady-state value of Induction motor is resistant to resistance variation and time delay effect. Small-signal analysis is done to further improve the performance of the system and also its stability. The improper alternative of the resistance value and Adaptation gain value may result unreliable at low-speed Recurring mode. In order to achieve Substantial operation, the stator resistance is diversified according to the quadrature axis current and frequency of the stator. The accuracy and validity of the proposed analysis is verified by simulation using both PI & ANFIS Controllers
