Speed-sensorless Direct Torque Control for Asynchronous Machine Based on Extended Kalman Filter

Permanent magnet synchronous motors (PMSM) are appropriate for applications with load-independent speeds or synchronous operation with high accuracy under defined speed. In this paper analysis the structure and equations of the PMSM, direct torque

This paper presents the sensorless direct torque control (DTC) technique for five-phase interior permanent magnet (IPM) motors. By using the introduced technique fast torque response with low ripple in the stator flux and torque of the five-p
