摘要
研究了计及时滞影响的电力系统稳定器(PSS)的H∞控制。基于H∞鲁棒控制理论和线性矩阵不等式处理方法,利用Matlab/LMI工具箱,以联接到远方系统的发电机为例,进行了时滞系统PSS的H∞控制器设计。应用Pade逼近法近似时间延迟,采用Matlab/Simulink技术进行数字仿真。仿真及分析表明,所设计的PSS具有很好的对时滞的不敏感性,可以抑制振荡,提高电力系统的稳定性。
The paper presents the design of H∞ control of PSS in consideration of time-delay by LMI technique. Based on MATLAB/LMI toolbox, the design of H∞ PSS for single machine distant power system is completed. By using of MATLAB/simulink and pade approximation,the simulation and analysis show that the controller can not only endure the time-delay, but also raise the dynamic stability of power system.
