Abstract:  In order to improve the image segmentation accuracy, and solve the problems in the traditional fuzzy For the issue that the parameter estimation of squirrel cage induction motor, a parameter estimation method based on the variable frequency excitation response test is proposed. First, when the rotor is at rest, a variable-frequency excitation signal with the frequency range 0.5 Hz to 150 Hz is applied to the two phases of motor through an AC voltage source. Then, the frequency response of the motor to these signals is measured, so as to estimates the resistance and inductance parameters of the motor single-cage and double-cage models. The actual speed and torque of the motor are measured by experiments, and the results are compared with the calculated speed and torque based on estimated parameters. The results show the effectiveness of the method.

摘要： 针对鼠笼式异步电机的参数估计问题，提出一种基于变频激励响应测试的参数估计方法。首先，当转子静止时，通过一个交流电压源向电机两相施加一个变频激励信号，频率范围为0.5 Hz到150 Hz。然后，测量电机对这些信号的频率响应，并以此来估计出电机单笼和双笼模型的电阻和电感参数。通过实验测量电机的实际转速和转矩，并将其与根据估计参数所计算的转速和转矩进行对比，结果证明了该方法的有效性。
