A novel sliding hysteresis band based Direct Torque control scheme for PMSM motors to achieve improved current THD with reduction in torque and flux ripples eliminating the low-speed problems

The performance of Direct Torque Controlled (DTC) Permanent Magnet Synchronous Motor (PMSM) is severely hampered by high Total Harmonic Distortion (THD) in motor current, especially under low-speed operations. Current THD problems show up as torque ripple, elevated losses, temperature rise, low powe...
