简介：这篇论文与变化时间的延期探讨polytopic系统的Hankel标准。延期依赖者足够的条件被介绍以便polytopic系统是稳定的，polytopic系统的Hankel标准是不到规定数量以线性矩阵不平等。一个数字例子被举。

简介：与pointwise为连续时间的系统过滤的H的问题变化时间的延期在这份报纸被调查。由在Krein空间使用革新分析，为一个H过滤器的存在的一个必要、足够的条件在二个方法被导出：一个人是部分微分方程途径，其它是重新组织的革新分析途径。前者把一个答案给与边界条件以一个部分微分方程的答案过滤问题的建议H。以后把一个分析答案给以Riccati和矩阵的答案过滤问题的建议H微分方程。

简介：有混合变化时间的延期的不明确的中立系统的柔韧的稳定性在这篇论文被调查。在考虑下面的不确定性围住标准、变化时间。基于Lyapunov稳定性理论，一个延期依赖者稳定性标准在线性矩阵不平等(LMI)形式被导出并且给。最后，一个数字例子被给在一些存在结果上说明重要改进。

简介：在这篇论文，我们与州的延期处理不明确的变化时间的非线性的系统的一个班。在一些假设下面，我们构造稳定连续反馈的一些，即处于状态线性、非线性，它能保证全球制服得到指数的稳定性和考虑系统的全球一致实际集中。为名字的稳定的系统的二次的Lyapunov函数为全球系统被用作一个Lyapunov候选人函数。在这笔记开发的结果对有不明确的时间延期的动态系统的一个班适用。我们的结果被一个数字例子说明。
