Original Abstract
The aim of this paper is to present the algorithm for online stator resistance estimation of AC induction motor. It can be used along with any control algorithm. It looks for steady state operation when the voltages and currents are harmonic. The stator resistance estimate is realized using RMS values of voltage and current and using actual active power. The main goal of this algorithm is to catch up the slow changes of stator resistance caused by temperature changes. From this point of view it would be suitable for sensorless vector control algorithms of AC induction motors because the good knowledge of this parameter is crucial since it influences steady state error in rotational speed and also the stability of the velocity estimation.
