The term sensorless vector control means vector control without any speed sensor. Sensorless vector control drives have main benefits over vector control drives as reliability and low cost. Speed of the motor can be estimated using Motor terminal voltages and currents. If we know the certain parameters of the induction motor, using these parameters and reference frame theory we can construct the mathematical model of motor. This model is used for speed estimation. In this paper speed of induction motor is estimated using model reference adaptive system and system is simulated using MATLAB. Simulation results of estimated speed is correct.
