本文提出一种简练形象且易于理解的异步电机动态复数矢量模型及其等效电路,并与动态矩阵模型形成相互印证。将三相全控桥和笼型异步机作为一个整体,解析了异步电机的转子磁链定向控制策略,对学生理解和研发基于动态数学模型的高性能异步电机调速系统具有现实意义。
The dynamic complex vector mathematical model and its equivalent circuit of the asynchronous motor is proposed in this paper, It can be confirmed with dynamic matrix mathematical model mutually. The rotor flux link- age oriented control stategy for the asynchronous motor is analyzed with the three-phase full-bridge converter and the squirrel-cage asynchronous motor as a whole, which has important significance for understanding and applying the dynamic mathematical model of the high performance asynchronous motor control system profoundly.
