摘要
利用二次稳定的概念 ,研究了带有外部干扰的离散广义系统鲁棒控制器的设计问题 .在对系统进行二次稳定分析的基础上 ,给出了系统可以鲁棒镇定的条件 ,并且这一条件被表示为线性矩阵不等式 (LMI)的形式 。
Using the quadratic stability,the design of robust controller for discrete-time singular systems with exogenous disturbance is discussed in the paper.Based on the analysis of quadratic stability for the systems,a sufficient condition of robust stabilization is estblished in terms of linear matrix inequality.The problem of design of robust feedback controller can be solved on the basis of LMI techniques.
