中文摘要：
为改善带整流负载的同步电机的运行稳定性，在电机转子中设置了交轴短路绕组。建立了带交轴短路绕组同步电机的参数辨识模型，研究了利用最小二乘法实现参数的辨识，分析了待辨识参数的灵敏度。根据参数灵敏度大小，局部辨识了某电机的参数。结果表明，该方法是有效的。
英文摘要：
The quadrature-axis short-circuit winding was installed in the synchronous machine to improve stability of system. Based on the basic theory of electric machines, the identification mathematical model of the synchronous machine with quadrature-axis short-circuit winding in d-q coordinate was established. The identification method of least squares was analyzed and the parameters of a realistic machine were partially estimated with the sensitivity analysis of the parameters. The estimation parameters agree quite well with the given parameters, showing that the measurement method presented is correct.
