This paper presents a nonlinear robust adaptive excitation control design procedure for multi machine power systems using back-stepping method. The control objective is to drive machine power angle and frequency to the steady-state operation point, and guarantee that the close-loop system is adaptive to the uncertainties of generator damping coefficient and d-axis reactance, and robust to model errors or bounded disturbances.

利用反步法设计了多机电力系统中的非线性鲁棒自适应励磁控制方案，控制目标是调节发电机功角和频率至稳态运行点的极小领域，并使闭环系统对发电机阻尼系数和电抗参数的不确定性具有自适应能力，且对模型误差和外部有界干扰具备鲁棒性，同时保证各控制器是分散化和本地化的。

What do you know about the Battle of Little Big Horn?

你对「小大角之战」有多少认识呢？

Do you know the story of the famous battle at Little Big Horn, Montana?

因为在小大角区内发现了黄金的踪迹，所以美国政府想要兴建一条道路，穿越蒙大拿境内的原住民土地。

A series of " Powder River " skirmishes culminated in the 1876 Battle of Little Big Horn against General Custer, which made leaders such as Crazy Horse famous.

1876年爆发的小大角山战役将保德河附近发生的一系列小规模冲突推上了高潮。这场针对卡斯特将军战争同时使疯马等印第安人领袖闻名于世。
