Nonlinear Continuous Variable Structure Control for Generator Excitation

本文深入研究了一种连续变结构控制规律，进一步讨论了其稳定性和特点，它保留了传统变结构控制的优点，并较大地增强了鲁棒性且克服了颤振问题。将该方法引人到电力系统，设计了发电机励磁非线性连续变结构控制器。数字仿真结果显示了该控制规律可以显著地改善系统的动态特性，同时具有较强的鲁棒性，表明了所提控制规律的有效性。

A continuous variable structure control law is studied. The approach retains the positive properties of classical sliding mode control,and increases the robustness but without the disadvantage of control chattering.The control law is introduced to power system,and generator excitation nonlinear continuous variable structure control law is proposed.The results of computer simulation show the validity and effectiveness of the control approach.
