This paper proposed a method of stator resistance estimation for sensorless induction motor (IM) drives based on a model reference adaptive system (MRAS). In this scheme, the error between estimated stator current and real stator current is regarded as the system error to estimate the rotor speed. Because of the motor parameters vary with inner temperature of the motor, the influence of motor speed estimation due to stator resistance identification error was analyzed. The error compensation method for stator resistance estimation was proposed. The algorithm is given to compensate the stator resistance deviation, which results in the speed estimation error. Simulation and experimental results show the good performance for the proposed scheme in speed and robustness for sensorless induction motor drives.
