摘要
异步电机是一个高阶、非线性、强耦合的多变量系统，矢量变换控制能使其解耦．本文分析了矢量控制系统正确解耦的充要条件，即磁链定位偏差角δ＝０°；提出了直接观测解耦充要条件的方法；研制了模型参考自适应实验系统．
An induction Motor is a multi variable system of high order, non linear, and strongly coupled one. It can be decoupled by vector control. In this paper, the flux orientation angle deviation δ =0°, which is the sufficient essential condition for the vector control system to be accurately decoupled, is discussed, and the method for observing this condition directly is also proposed. Furthermore, an experimental Model Reference Adaptive System is studied and completed. Based on it, some experiments have been developed. The results demonstrate the correctness of theoretical analysis.
