Abstract :
A novel model reference adaptive system based stator resistance estimation algorithm has been proposed in this paper. A new functional candidate is introduced which is positive definite and does not depend on speed information for resistance estimation. This formulation decouples stator resistance and speed estimation in case of a Q-MRAS based sensorless drive. Also, restriction on selection of estimator gains becomes less rigid when the proposed estimator is used for stator resistance compensation in an X-MRAS based drive. Extensive simulation using MATLAB/SIMULINK and experimentation in dSPACE 1104 based laboratory prototype has confirmed the effectiveness of the proposed technique.
