Abstract
In this paper, a detailed study of the performance of Vector Controlled Induction Motor drive with Model Reference Adaptive System (MRAS) based Rotor Resistance Estimator using Reactive Power is presented. The rotor resistance changes significantly during operation due to temperature rise. This variation has a major influence on the field oriented control performance of an induction motor drive due to the deviation of slip frequency from the set value. The MRAS approach using reactive power as a functional candidate for rotor resistance estimation makes it computationally simpler, easy to design. Rotor resistance estimation using reactive power completely eliminates the need of flux estimation. Thus, this method is less sensitive to integrator - related problems. The performance of vector controlled induction motor drive with the MRAS based rotor resistance estimator is simulated in MATLAB/SIMULINK. The promising results obtained are presented.
