研究了无刷双馈电机（BDFM）直接转矩的控制（DTC）策略，在传统直接转矩控制方法的基础上，利用离散空间电压矢量调制（DSVM）技术，给出了基于改进模糊控制策略的无刷双馈电机的直接转矩控制方法。系统仿真结果表明该控制系统低速特性和传统控制策略相比有很大提高，控制准确，能够满足电机从亚同步状态到超同步状态的运行需求。

The direct torque control （DTC） strategy of brushless double-fed machine （BDFM） is studied. The improved DTC fuzzy control strategy of BDFM on the basis of conventional direct torque control and discrete space voltage vector modulation （DSVM） technology is presented. The simulation results indicate that the control system can efficiently reduce the torque ripple and improve the low-speed characteristics of the system compared to the conventional strategy. This system controlled accurately and can meet the motor operation demand from synchronization to super synchronous state.
