介绍了根据无源性控制原理设计变结构控制器的一般步骤和方法，得到一种直接针对非线性模型设计发电机励磁控制器的方法。由于在控制器的设计中，未用到任何线性化方法，因而所得控制器充分利用了系统的非线性特性。仿真证实了其能有效地改善电力系统的稳定性，且控制规律对系统工作点的变化具有强鲁棒性。

Synchronous generator excitation control based on passivity

The method and steps to design variable-structure controller based on passivity principle are described and analyzed. Using the designed trajectory,a generalized method for generator excitation controller design based on the nonlinear model is developed. Since the design is based on the nonlinear dynamic system without any linearization,the nonlinear property of the system is completely used for nonlinear robust robust controller. Simulations prove that the proposed control law improves the power system stability and the control principle is robust to the change of system working point.
