摘　　要：矢量控制得以有效实现的基础在于异步电机磁链信息的准确获取,实用系统中多采用容易实测的电压、电流或转速等物理量的不同组合,形成多种磁链的观测模型来获得磁链信息。电压模型、电流模型和组合模型是典型的三种开环观测模型。通过设计仿真实验,得到各种模型的优缺点及其适用范围,并且与理想模型进行比较,得出这三种模型对磁通的观测是切实可行的。The effective vector control of Asynchronous Motor depends on the accurate acquirement of its Flux. Because the practical system mostly makes use of associations of voltage, current and speed measured more easily, builds up the observation model with various flux linkages to acquire their information. There are three open loop observation models including voltage, current and combined models. Simulation experiments can obtain merits and faults and applicability of various models, and proves that the establishment of three models is feasible for observing flux compared with ideal models.
