Abstract :
In this paper, a detailed study of the performance of rotor flux and reactive power based MRAS rotor resistance estimators for Vector Controlled Induction Motor drive is presented. The rotor resistance changes significantly during operation of the drive due to temperature rise and saturation. This variation has a major influence on the performance of the field oriented control of induction motor drive. The MRAS approach using reactive power as a functional candidate for rotor resistance estimation makes it computationally simpler, easy to design when compared to the other methods available for rotor resistance estimation. In this paper, two types of MRAS methods using flux and reactive power based rotor resistance estimation technique for Vector Controlled Induction Motor Drive is designed and validated through MATLAB/SIMULINK simulation. The performance of Vector Controlled Induction Motor drive with MRAS based rotor resistance estimators are analysed extensively. The comparison shows the superiority of the reactive power based Rr estimator in terms of accuracy, settling time, and stator resistance dependency. The results obtained are presented.
