An Implementation of Direct Torque and Flux Control for Low Power Permanent Magnet Synchronous Motor Drives

Sanda Victorinne Paturca, Ioana Raluca Adochiei

This paper presents an implementation of Direct Torque and Flux Control (DTC) scheme for Permanent Magnet Synchronous Motor (PMSM) drive, focusing on the development of the digital control. The control was designed so that to allow accurate sampling related to control update time, considering in addition a measurement scheme common to the low power drives. Simulation and experimental results are presented to sustain the solution proposed for digital control implementation.
