摘要
介绍了具有闭环区域极点约束的汽轮发电机组汽门开度的H∞控制,并以实例说明利用线性矩阵不等式(LMI)求解的方法。仿真及分析表明,所设计的汽门开度的H∞控制方法不仅能提高电力系统的暂态稳定,并且能抑制低频振荡,改善动态品质。
This paper presents the design of H∞ control for steam-valving system of steam turbo-generator sets with closedloop regional pole constraint. The solving method utilizing linear matrix inequality （LMI） is illustrated. Simulation and analysis show that the H∞ controller improves not only the transient stability of power system but also the character for damped low-frequency oscillation.
