| 摘 要： | 为了提高发电机励磁控制器的控制效果，提出了一种将基于机端电压偏差的比例积分控制和基于微分几何理论的非线性励磁控制相结合的改善机端电压的非线性励磁控制器设计方法。为验证方法的有效性，用MATLAB进行仿真试验。仿真结果表明，所设计的非线性励磁控制器在小扰动和大扰动情况下不仅能较好地保证发电机角速度、功角的稳定，而且能改善机端电压的精度和稳定度。

| Abstract: | In order to improve the control effect of the generator excitation controller,this paper proposes a design method of nonlinear excitation control to improve the terminal voltage by combining the terminal voltage deviation based PI control with differential geometric theory based nonlinear excitation control. MATLAB is used for simula-tion,the results show that in a small and large disturbance cases the proposed nonlinear excitation controller can not only ensure the stability of angular speed and angle of the generator,but also improve the precision and stabili-ty of the terminal voltage. |
