| 摘 要： | 针对异步电机运行参数时变性影响磁链的准确计算,提出了用非线性处理函数构成的多层网络,具有对任意函数良好的逼近能力来对异步电机的转子磁链和转速进行辨识,构成了异步电机的地矢量控制系统。系统仿真表明,这种方法能较好的辨识电机的转子磁链和转速,具有良好的动态性能。

| Abstract: | In view of the time-variation of running parameters of asynchronous motor,influences the accuracy of flux linkage calculation.A method of using multilayer network composed of nonlinear processing function with the good ability of approaching arbitrary function to identify the rotor's flux linkage and rotational speed of asynchronous motor is put forward,and forms a vector control system.The method can identify the rotor's flux linkage and rotational speed well and possesses good dynamic properties. |
