Firstly it is introduced that traditional generator excitation controllers and elaborated non-linear control theory developed more quickly in resent years, then studied the non-linear excitation controller design on single machine infinity bus power system. 本文首先介绍传统的发电机励磁控制器,阐述了近年来快速发展的非线性控制理论,然后深入研究了单机无穷大母线电力系统非线性励磁控制器的设计。
