摘　　要：本文以电力系统的非线性模型为基础，依据Ｈ∞控制理论及状态反馈线性化的方法，提出了一种电力系统鲁棒非线性励磁调节器设计的新方法。计算机仿真研究表明，鲁棒非线性励磁调节器不仅可以有效地改善系统的动态特性，而且在提高电力系统稳定性，尤其是大干扰稳定性方面有明显的作用。The robust control problem of power systemis investigated in this paper. A novel controller for the generator excitation system is set up based on a combination ofH∞ control theory and feedback linearization approach. Theproperties of the controller are its complete decentralizationand robustness. The design is well suited to a multimachinesystem where it is not based on a infinite-bus aproximation.Simulation performed on a 13-machine system shows thatthe proposed controller can not only improve the dynamicperformance of the power system, but also can enhance thesystem stability, especially the stability against Iarge disturbance.
