摘　　要：首先建立了复合笼条转子异步电动机的数学模型,然后利用推广的卡尔曼滤波法,将模型中转子电阻和漏感增广为状态变量,对其进行了辨识。利用辨识得到的参数对电机的起动过程进行了仿真。将复合笼条转子感应电机的转子参数及仿真结果与普通感应电动机进行了比较,说明复合笼条转子异步电动机良好的起动性能。In this paper, the mathematic model of induction machine with compound cage rotor is built up. Using the extended Kalman filtering, rotor resistance and leakage inductance are extended as state quantity and are identified. Based on the identified parameters, simulation studies are performed. The rotor parameters and simulation result of induction motor with compound cage rotor are compared with common induction motor. It can be showed that induction motor with compound cage rotor is of good starting performance.
