摘　　要：利用传统直接转矩控制技术,会导致开关磁阻电机稳态定子电流幅值大,电机铜耗增加。基于模糊自适应技术,研究了一种磁链自适应直接转矩控制方法,通过建立给定定子磁链与转速之间的联系,实现磁链的自动调节。实验结果证明,该控制方法能有效减小稳态时定子电流,转矩脉动显著降低。The current amplitude of state statorfor switched reluctance motor is relatively large based on the traditional DTC technology,then the copper consumption of the motor increases. Based on the fuzzy adaptive technique,a flux- linkage adaptive direct torque control was researched in this paper. It realized the automatic adjustment of the flux- linkage by establishing the link between the stator flux linkage and the speed. The experimental results show that the method reduces the current amplitude effectively,and the torque ripple is reduced significantly.
