摘要:
无刷直流电机直接转矩控制由于反电势非正弦以及两相导通模式,产生较大的换相转矩脉动. 本文提出一种优化的无刷直流电机直接转矩控制电压矢量选择表,有效降低了换相转矩脉动幅值. 通过数学推导对新定义的不同零电压矢量在换相过程所产生的换相转矩脉动进行对比分析. 结果显示,通过上管和下管零矢量的组合使用,换相转矩脉动可以得到有效抑制. 仿真及实验结果验证了理论分析的正确性.
Abstract:
Brushless DC motors have the problem of high torque ripple in direct torque control system because of the non-sinusoidal back EMF and two-phase conduction mode. Aiming at reducing the torque ripple in DTC system of BLDCM,the paper proposes an optimized voltage vector selection table. The commutation torque ripple of the different new zero voltage vectors are analyzed and compared by formula deduction. The result shows the commutation torque ripple is effectively suppressed through the combination between upper and lower zero voltage vectors. The simulation and experiment verifies the theoretical analysis.
