A step forward for motor torque controllers: In order to reduce oscillations and oversets, a speed loop pseudo derivative feed forward controller is proposed

The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...
