In this paper a Model Reference Adaptive System (MRAS) is presented as the speed estimation technique in which the error speed is estimated by comparing reference model and adaptive model and further the error speed is used to obtain the rotor speed. Proportional Integral (PI) is designed for controlling purpose. A non-linear fuzzy-PI controller is used to optimize the speed error value. The Proposed MRAS based speed sensorless control of Induction Motor (IM) drive will ensure the better dynamic performance and reliability, compared to conventional methods. The proposed scheme is simulated using MATLAB/Simulink software.
