摘　　要：在矢量控制和直接转矩控制的基础上,提出一种异步电动机按定子磁场定向控制的方法,采用定子电阻压降补偿和电流转矩分量的闭环控制,实现了定子磁链的控制。基于定子磁链处于稳态时,转子电流矢量应与转子磁链矢量垂直的原则,提出了一种闭环形式的定子电阻在线调整方法,仿真结果充分验证了该方法的可行性。A new control strategy of asynchronous motors with stator flux orientation that combines the advantages of both vector control and direct torque control were presented. According to the dynamic model of asynchronous motors,stator flux was controlled respectively. Based on the vertical relation between rotor current vector and rotor flux vector when stator flux was in steady-state,a closed-loop stator resistance on-line tuning method was presented. The experimental results fully confirmed the feasibility of the method.
