  abstract     = {{Brushless DC motor drives are typically employed in speed controlled applications. Torque control, particularly during regenerative mode, is not the standard domain of BLDC drives. However, it can be shown that the known BLDC control approach can be extended to control the torque in the regenerative mode even for low speed or at standstill. A hysteresis controller is proposed, which is specified by means of a state chart.}},
