直接转矩控制方法的探析

Direct Torque Control Method

针对传统直接转矩控制方法的不足,在转矩脉动、磁链观测、开关状态选择、谐波抑制及控制性能改善等方面提出优化或改进措施,以有助于实现更优的设计方法。

In view of the defects existed in traditional direct torque control method, the corresponding measures for optimizing and improving are summarized in aspects of torque ripple, flux-linkage observation, selection of switching state, harmonic suppression and improvement of control performance., which helps for further optimization of the design method.
