摘　　要：电机数学模型的参数直接影响无速度传感器矢量控制系统的性能。从异步电机动态数学模型及实际使用情况出发,提出了一种在被控电机静止的状态下借助FFT及复数运算对电机参数进行辨识的方法。试验结果证明此方法简单可行,能为无速度传感器矢量控制系统提供较高精度的电机参数。The parameter of motor mathematical model influences the performance no speed sensor vector control system. An identification method in a controlled motor static state by means of FFT and complex operation for identification of the motor parameters under the model of asynchronous motor and the actual application situation were introduced. The test resuhs proved that this method was simple and practical. It could provide a highly precision motor parameters for the vector control system of no speed sensor.
