| 摘要: |
| 同步电机的参数辨识问题在数学上可以被看成是一种非线性反问题，而反问题需要解决的首要问题就是它的病态性问题。通过对反问题的病态性问题进行分析，将Tikhonov正则化方法引入到同步电机参数的辨识中。在仿真中设置多个测试场景，仿真结果表明，与传统的最小二乘参数辨识法相比，所提方法能克服系统的病态性并有效地对电机参数进行辨识。 |

| Abstract: |
| The synchronous generator parameter identification can be mathematically regarded as a nonlinear inverse problem and the primary issue is its ill condition. The ill condition of inverse problem is analyzed and Tikhonov regularization method is introduced to the identification of synchronous generator parameters. Multiple test scenes are set in simulation and the simulative results show that，compared with the traditional least square method，the proposed method can overcome the ill condition of system and identify the parameters of synchronous generator effectively. |
