感应电动机参数的卡尔曼滤波法辩识

本文首先建立了异步电动机的数学模型，然后利用推广卡尔曼滤波法，将模型中转子电阻和漏感增广为状态变量，对其进行了辩识。在辩识中，对非线性系统局部线性化的参考点进行了迭代。最后，得到了参数辩识结果，并与常规空载、短路的实测结果进行了比较。

Parameters Indentification on Induction Machine Based on Kalman Filering Method

In this paper,the mathematic model of induction machine is built up.Using the extended kalman filtering,rotor resistance and leakage inductance are extended as state quantity and are identified.In the process of identification,the reference point where the non-linearity system is linearized is calculated repeatly.At last,the result of parameters identification is got and the result is compared with that of the common non-load and locked-rotor tests.
