摘　　要：较系统地介绍了电力系统鲁棒励磁控制器的设计方法。给出单机无穷大系统中水轮发电机组的线性化模型，在此基础上推导出了所研究系统的状态空间描述，并按鲁棒控制理论设计了鲁棒励磁控制器。最后，用放计算机仿真的方法对该控制器进行了研究，结果表明线性鲁棒励磁控制器在稳定系统方面优于线性最优励磁控制器。A method for designing robust exciting controller for power system is presented in this paper. Firstly,a linearized hydro turbine generator system model of single machine infinite (SMIB) system is developed. Next, based on the lineared model, the calculation of state space descriptions and a new method for design robust hydro turbine generator exciting controller is proposed. Finally, resorting to computer simulation, a comparison is made to show that the robust exciting controller have an advantage over the linear optimal exciting controller.
