摘　　要：以电力系统的非线性数学模型为基础，根据直接反馈线性化与滑模变结构控制理论，提出了一种旨在提高电力系统稳定性的由直接反馈线性化与滑模变结构混合控制完成的电力系统同步发电机励磁控制器．仿真研究表明，所提出的励磁控制器不仅可以有效地改善系统的动态品质，而且在提高电力系统的稳定性，尤其是大干扰稳定性方面有明显的作用．A hybrid feedback linearizing control and sliding control scheme is employed for the design of the excitation controller to improve the stability of power systems,based on the third order generator model.The computer simulation study on a 13 machine system shows that the proposed excitation controller possesses better performance than the conventional power system stabilizer both in the improvement of dynamic performance of the power system and in the enhancement of the system stability,especially the stability against large disturbance.
