This paper deals with the problem of robust stabilizationfor the systems with rank-1 type uncertainties and mul-tiple state delay.Firstly,a new delay-dependent crite-ria is presented for unforced normal delayed system to bestable.Based on the obtained criteria,a new LMI ap-proach is developed for robust stabilization of a class ofuncertain delay systems via linear memoryless state feed-back control law.The results depend on the size of thedelays and are given in terms of linear matrix inequali-ties.And so no tuning procedure for scalars and/or ma-trices is required and the results are less conservativethan those of delay-independent.Finally,an illustra-tive example is presented. 相似文献

This paper deals with the problem of decentralized robustcontrol for a class of interconnected uncertain systemswith state delays.The parameter uncertainties are un-known but norm-bounded.A new sufficient condition isobtained for each subsystem and overall system to be sta-bilizable via linear memoryless state feedback robust de-centralized controllers.The results depend on the size of the delays and are given in terms of linear matrix ine-qualities,so they are less conservative than those of delay-independent.Moreover,matching condition is not a necessary condition.Finally,an example is presented to illustrative the effectiveness of the proposed method. 相似文献

研究时滞不确定性系统的鲁棒镇定问题。镇系统具有多重状态时滞和多重控制时滞,其不确定性满足范数有界条件。利用线性矩阵不等式方法,得到了这类系统可状态反馈镇定的充分条件。通过解一个线性矩阵不等式,即可得到所需的控制器。最后用一例题说明了本文方法的有效性和较黎卡提方程方法的优越性。 相似文献

This paper deals with the problem of robust H∞ control for uncertain systems with multiple state delays. The parameter uncertainties are unknown but norm - bounded. An LMI based method is developed for robust H∞ stabilization for a class of uncertain systems with multiple state delays via linear memoryless state feedback control. The resuits depend on the size of the delays and are given in terms of linear matrix inequalities, so they are less con. servative than those of delay - independent. 相似文献

一般的参数估计往往对分布的偏差很敏感,对于带有一个误差项的系统,鲁棒参数估计方法能较好地解决这一问题.这里基于极小极大方法,给出了带有两个误差项线性回归模型的鲁棒参数估计. 相似文献
