Conventional single-vector-based direct torque control (SVB-DTC) has been widely researched owing to its simple control structure, parameter robustness and fast response. However, the SVB-DTC often features large torque and flux ripple. To suppress the large ripple in torque and stator flux, recently, a duty-cycle-based DTC (DCB-DTC) scheme applying a zero vector and a nonzero vector to the drive...
Conventional direct torque control (DTC) achieves faster dynamic response compared to field-oriented control in permanent magnet synchronous motor drives (PMSM). However, it usually features large torque and stator flux ripple which deteriorates the steady performance of PSM drive. Various duty- based DTC schemes have been proposed to reduce torque ripple at the expense of increased complexity and...
