【摘要】 讨论了一类具有模态转移率不确定性的Markov跳变时滞系统的鲁棒输出跟踪控制问题。利用松弛权矩阵方法,提出保证系统随机稳定且满足给定H∞跟踪性能的充分条件。该条件和控制器的优化设计方案可归结为一组线性矩阵不等式(LMI)的可解性问题。此外还给出了系统模态转移率的允许摄动上界数值条件。更多还原

【Abstract】 The robust output feedback control problem is studied for a class of Markovian jump time-delay systems with un-certain switching probabilities.Sufficent conditions on the stochastic stability with prescribed H∞ tracking performance are proposed using a slack weighting matix method.The conditions and the optimial design of the controller are formulated as a set of direct linear matrix inequalities(LMIs).Further more,the tolerable bound of the perturbation of the mode transition rates is also presented.更多还原
