研究了一类连续时滞系统的时滞相关非脆弱H∞鲁棒控制问题。所考虑的附加增益变化包含在控制器增益和obhsiunserver增益中。利用李雅普诺夫泛函方法，得到了非脆弱H∞控制系统的时滞相关稳定性判据.控制器和观测器的增益由LMI可行解给出。基于本文的结果，在设计非脆弱H∞控制器时，矩阵等式约束是不必要的。计算机软件Matlab可以应用于解决所有提出的结果。最后通过一个数值例子说明了本文的改进。
The problem of the delay-dependent non-fragile H∞observer-based control for a class of continuous time-delay systems is investigated in this paper. The additive gain variations under consideration are contained in both the controller gain and obhsiunserver gain. Delay-dependent criteria are derived to guarantee the stability of the non-fragile H∞observer-based control system using the Lyapunov functional approach. The controller and observer gains are given from the LMI feasible solutions. Based on the result of this paper, the constraint of matrix equality is not necessary for designing the non-fragile H∞observer-based controls. Computer software Matlab can be applied to solve all the proposed results. Finally, a numerical example is illustrated to show the improvement of this paper.
