 Description: EKF- BASED SENSORLESS DIRECT TORQUE CONTROL OF PERMANENT MAGNET SYNCHRONOUS MOTOR: COMPARISON BETWEEN TWO DIFFERENT SELECTION TABLES-In this paper a sensorless direct torque control (DTC) scheme of permanent magnet synchronous motor (PMSM) is proposed. To improve the performance of the classical DTC a modified control scheme based on twelve sectors instead of six is presented and a comparison between the two methods is carried out. The high performance of the DTC is related to the accuracy of the flux estimation witch is affected by parameter variation especially the stator resistance due changes in temperature or frequency.
