Single Sensor Based Vector Controlled PMSM Drive

This paper presents the current-sensorless, with position sensor-based vector-controlled PMSM (Permanent-Magnet-Synchronous-Motor) drive. The stator-currents are estimated in rotor-reference ( iqs, and ids) frame from the reference-voltages ( vds and vqs). The single-position/speed sensor is used in the drive. The same is simulated and verified in MATLAB/SIMULINK and in Real Time Typhoon Hardware In Loop (HIL) 402 platform for various speed and load.
