摘要
针对一类不确定时滞广义系统,基于线性矩阵不等式(LMI)方法,研究了被控对象和控制器同时存在摄动时的保性能和最优保性能控制器的设计问题。给出了广义系统弹性保性能的充要条件及相应的控制器的设计方法,数值例子验证了该方法的可行性。
In this paper,based on linear matrix inequality （LMI） method, the problem of guaranteed cost control and optimal guaranteed cost control for a class of uncertain time-delayed descriptor system is addressed, where the uncertainties exist both in the systematic matrix, and in the controller gain. The sufficient and necessary condition of non-fragile guaranteed cost and corresponding controller designs are presented. A numerical example is given to illustrate the effectiveness of the design method.
