根据发电机励磁控制的任务，本文基于微分几何控制理论提出了一种新的非线性励磁控制器的设计方法。应用该方法设计的非线性励磁控制器不仅可以有效地改善电力系统的稳定性，而且还可以满足电压精度调节的要求。实例仿真结果表明，该种控制器与已有的非线性励磁控制器相比，在改善稳定性的同时，防止了电压超调现象。

According to the task of generator excitation control,this paper poposed a new design method of nonlinear excitation controller based differential geometric thaory. The nonlinear excitation controller thus obatined can not only effectively improve the power system stability,but also satisfy the requirement of voltage regulation accuracy. The simulation results on examples show that this proposed controller can prevents voltage overshoot while improving stability simultaneously,compared with the existing excitation controllers.
