摘要
提出一种双折角调制三十边形磁链轨迹直接自控制方法,它通过增加折角以及选择合适的定子磁链轨迹,减小定子电流和磁链的主要低次谐波。理论和实验结果表明,相比较于传统十八边形磁链轨迹直接转矩控制,所提出的控制方法保持经典直接自控制简洁优点的同时,它使得该方式下的定子电流和磁链的谐波含量进一步减小,控制性能得以改善。
A novel direct self control（DSC） strategy of 30-angular flux trace based on double fold corner modulation is proposed in this paper,which reduce all low dominating harmonics of the stator current and flux.This is achieved by increasing the stator flux corner and choose appropriate flux trajectory.The theoretical and experimental results show that the proposed method retains the advantages of concise in classic DSC and further reduce the dominating distortion in comparison to 18-corner DSC and improves the control performance.
