摘要
在H2/H∞保性能控制理论和直接反馈线性化的基础上,文章研究了SVC(静止无功补偿器)的控制器设计,对具有SVC的单机-无穷大系统,建立了含不确定因素的数学模型。采用解LMI(线性矩阵不等式)方法,利用MAT- LAB/LMI工具箱,得出H2/H∞保性能控制律。分析表明这种控制方法兼有鲁棒性能和最优性能,降低了单纯H∞控制方法的保守性,提高了电力系统的稳定性,并能满足电压精度的要求。
The controller design of SVC based on H2/ H∞ guaranteed cost control theory and direct feedback linearization is presented. The robust control model of SVC in single-machine infinite-bus system is established. The H2/ H∞ control rule is obtained by MATLAB/LMI toolbox, The results demonstrate that the method of control possesses good adaptability and robustness. The stability feature of the power system is improved, The requirement of voltage regulation accuracy is ,satisfied.
