| 摘要: |
| 横向磁通永磁电机具有高转矩密度等优点,但其转矩脉动严重地影响了输出特性。提出一种改进的空间矢量直接转矩控制方法,并增加电压矢量数量及磁链区域的进一步细分,改变定子磁链和转矩的估测模型及磁链角的获取,使开关频率增加,转矩脉动减小,以削弱电流谐波,可有效地减小转矩脉动和磁链,电机得到平稳运行。将传统直接转矩与改进的空间矢量直接转矩控制进行对比研究,研究表明,改进的直接转矩控制减小了转矩脉动,增加了负载转矩,使横向磁通永磁电机工作性能得到提升。 |

| Abstract: |
| Transverse flux permanent magnet motor has the advantages of high torque density, but its torque ripple has seriously affected the output characteristics. An improved method of Space Vector Modulation-Direct Torque Control (SVM-DTC) is presented in this paper. It increases the voltage vector subdivision number and flux area, and changes the acquisition model and flux linkage angle estimation of stator flux and torque. The switching fre-quency increases, and the torque ripple is reduced.The current harmonic is weakened; this can effectively reduce the torque ripple and the flux linkage.The motor can run smoothly. The traditional DTC and the improved SVM-DTC are studied based on the TFPM motor. The results and their analysis show preliminarily that the SVM-DTC can re-duce the torque ripple, increase the load torque. The Performance of TFPM is improved. |
