- Abstract:
- Switched reluctance motor (SRM) had the advantages of simple structure, low cost and large star-ting torque, but it also had the disadvantage of large torque ripple. Direct torque control could reduce torque ripple of SRM, but there was torque runaway during commutation. In order to avoid it, it was necessary to optimize the direct torque control of SRM. The proposed paper combined the cubic torque sharing function with direct torque control, which aimed at synthesizing constant instantaneous torque and distributed the desired torque of each phase in different positions. Through torque hysteresis control, the synthetic instantaneous torque was tracked to the command torque output by the speed closed-loop controller to achieve balanced phase commutation and thus suppressed torque ripple, and subdivided six sectors of traditional direct torque control. Switch tables were optimized by adding transition voltage vectors, and torque runaway was avoided by combining magnetic link and torque double hysteresis control methods. Finally, the control method was verified by digital simulation and experiment. The results showed that when the motor speed reached 3 000 r/min and the load torque was 1 N·m, the torque ripple was reduced from 98.56% to 21.24%; When the load torque was 1.5 N·m, the torque ripple was reduced from 58.71% to 19.05%. The torque ripple of SRM was less than that of direct torque control.
