摘要
将非脆弱控制器的设计思想引入到一类含时滞的不确定奇异系统中,利用线性矩阵不等式(LMI)方法,研究被控对象与控制器同时存在扰动的非脆弱保性能控制问题。针对控制器存在加法式扰动情形,以线性矩阵不等式的约束条件给出了时滞奇异系统非脆弱保性能的充分条件,并以线性矩阵不等式的可行解给出了相应的控制器设计方法。数值算例说明此方法的可行性)。
The designation idea of non - fragile guaranteed cost controller is introduced to a class of uncertain descriptor system with time -delay. Based on linear matrix inequality（LMI） techniques, the problem of guaranteed cost control is addressed, where the uncertainties exist both in thw systematic matrix and in the controller gain. Under the additive pertubation, the sufficient condition of non - fragile guaranteed cost is presented, and the corresponding controller design is given in terms of the feasible solutions of LIMs. A numerical example is giver to illustrate the feasibility of the designed method.
