Abstract
The paper discusses impact of core loss on sensorless direct torque control (DTC) of an induction motor and develops a modified DTC scheme with full core loss compensation. Core loss is compensated in both the process of torque estimation and speed estimation. A novel modified speed estimator of MRAC type is developed for that purpose. The proposed compensated DTC scheme is verified by simulation.
