摘　　要：：本文以提高电力系统的正常运行水平和动态稳定性为目的，提出了一种变结构模型参考自适应励磁控制器。该控制器较好地利用了模型参考自适应控制所具有的对系统参数变化的适应能力和变结构控制所具有的对系统扰动的鲁律性特点，计算机仿真结果表明，本文所提出的顾磁控制器具有良好的动态品质，可以有效地改善系统的动态特性。A variable structure model reference adaptiveexcitation controller is proposed to improve the stability anddgnamic performance of the power system. The controllerpossesses the advantages of both variable structure control andadaptive control, which are robustness against disturbanceand adaptation to the parameter uncertainty of the power sys-tem. The simulation performance on an infinite bus systemshows that the proPosed controller can not only improve thedynamic Performance of the Power system, but also can en-hance the system stability.
