摘要
同步磁阻电机实际工作过程中d、q轴电感是随d、q轴电流变化的,故需要探究这种变化规律,进而根据同步磁阻电机数学模型来确定d、q轴电流的合理分配,优化矢量控制,实现最大转矩电流比。本文分析3种矢量控制方式,根据电机运行结果对比分析其控制性能。
In practical operation, the d- and q- axis inductances of the SynRM vary with the d- and q- axis currents. Therefore, it is necessary to investigate the variation relationship between the inductances and the currents, and then to properly determine the ratio between the d- and q- axis currents according to the Syn- RM mathematical model. In that way the vector control of the SynRM can be optimized, whilst the maximum torque per ampere can be achieved.
