这篇论文认为延期依赖者的问题指数在为有 polytopic 类型不确定性和变化时间的延期的随机的系统的吝啬的平方的稳定性。使用描述符模型转变并且介绍免费 weighting 矩阵, Lyapunov-Krasovskii 的一种新类型功能基于线性矩阵不平等(LMI ) 被构造,并且一些新延期依赖者标准被获得。这些标准包括 delay-independent/ratedependent 和 delay-dependent/rate-independent 指数的稳定性标准。这些新标准不比存在的保守。数字例子证明这些新标准是有效的并且是超过存在的改进。
This paper considers the problem of delay-dependent exponential stability in mean square for stochastic systems with polytopic-type uncertainties and time-varying delay. Applying the descriptor model transformation and introducing free weighting matrices, a new type of Lyapunov-Krasovskii functional is constructed based on linear matrix inequalities (LMIs), and some new delay-dependent criteria are obtained. These criteria include the delay-independent/rate- dependent and delay-dependent/rate-independent exponential stability criteria. These new criteria are less conservative than existing ones. Numerical examples demonstrate that these new criteria are effective and are an improvement over existing ones.
