By replacing with system function and holding x (t ), we also obtain two different stability criteia, then which is extended to structure uncertainty and polytopic uncertainty.
本章也通过对x(t)这一项采用保留或用系统方程替换这两种不同的处理方式,得到了两个不同的稳定性条件,同样地,将所获得的准则推广到结构不确定性系统和多胞不确定性系统。

通过将时变的网络延时分解成恒定的平均延时和不确定延时两部分,网络延时大于一个采样周期情况下的网络控制系统进而可建模成具有结构不确定性的离散时间模型。
