The 染小，功率可双向流动等优点，越来越受到人们的 experimental results show that through the use of torque and 关注[1-13] 。但是由于矩阵变换器的调制方法和开关 stator flux controllers based on variable-structure scheme can not 换流策略等方面的复杂性，目前实际应用于驱动感 only retain the fast torque response characteristics of traditional 应电机的矩阵变换器还很少。 direct torque control of induction motor driven by matrix 感应电机控制可分为标量控制和矢量控制[14] 。
