摘要: 提出线性离散时滞系统的耗散控制问题,研究无记忆状态反馈控制律存在的条件及 相应的控制器设计方法,以使相应的闭环系统渐近稳定,同时具有严格(Q,S,R)-耗散性.进 一步考虑耗散的不确定性,研究不确定系统鲁棒严格耗散控制的分析与综合问题.结果表明, 鲁棒耗散控制器存在的条件和综合问题等价于线性矩阵不等式(LMI)的可解性问题.Abstract: This paper focuses on the problem of dissipative control for linear discretetime systems with time-delay. The objective is to design memoryless state feedback controllers such that the closed-loop system achieves internal stability and strict (Q, S,R)-dissipativeness. The existence of the dissipative controller depends on the feasibility of linear matrix inequality (LMI). Furthermore, for uncertain systems characterized by dissipative uncertainty, the results of analysis and synthesis for robust dissipative strict control are then obtained in terms of LMI.
