摘要
文章研究了具有状态滞后的线性区间时滞系统的H∞鲁棒控制问题。通过把系统状态矩阵在区间内的不确定形式转换成可范数分解形式,获得了一种基于线性矩阵不等式(LMI)的设计鲁棒日∞控制器的方法。该控制器不但保证闭环系统渐近稳定,还可保证区间时滞系统的H∞范数限有界。
This paper deals with the problem of robust H∞ control of interval systems with state time-delay. We can gain a new method of designing robust H∞ controller by transferring the state matrices from uncertain forms in intervals to the norm-bounded decomposition forms.The controller above depends on linear matrix inequalities(LMIs) ,and it not only assures the close-loop systems are asymptotically stable but also guarantees the transfonners from perturbation to output of the interval systems are H∞ norm-bounded.
