摘　　要：分步总结了间接矢量控制的原理和算法,对异步电动机控制的"转矩产生"环节中电动机参数变化对电磁转矩和转子磁链的解耦控制带来的影响进行了详细的数学推导和分析,结合Matlab编程语言绘制出参数变化时的曲线,得到开环和闭环工况下的电磁转矩和转子磁链参数敏感性以及最大转矩特性。为异步电动机矢量控制系统的设计尤其是参数辨识和补偿提供参考,而不需要复杂的计算。This paper summarizes the theory and algorithm of indirect vector control step by step. Based on this, then the decoupling control variations of electromagnetic torque and rotor flux linkage in the torque control loop caused by motor parameters detuning are mathematically deduced and analyzed in detail. The detuning curves are derived by using Matlab programming language, open and close loop of electromagnetic torque and rotor flux linkage parameter sensitivity, as well as maximum torque characteristics are given. The results achieved from this paper can give a reference to the asynchronous motor vector control system design, especially parameter estimation and compensation, without complex calculation.
