Bezsenzorski pogon za vuču s estimatorima u kliznom režimu i MRASCC-u koristeći izravno upravljanje momentom

摘要

In the paper two types of speed, torque and flux estimators are described. The Sliding Mode Observer (SMO) and the Model Reference Adaptive System (MRAS) type estimators are applied in the sensorless Direct Torque Control with Space Vector Modulation algorithm (DTC-SVM) of Induction Motor (IM) drive. Dynamical performance of the drive and the estimator properties in field weakening and low speed regions for traction drive system are presented.
