研究具有随机丢包和时变时延的网络控制系统(NCSs)的建模和镇定控制问题。具体地说，采用了一种新颖的具有变时滞的马尔可夫跳跃线性系统对网络控制系统进行建模。在不使用增广状态方法的情况下，利用依赖于模式的Lyapunov函数方法，得到了具有分组丢失和时变时延的网络控制系统随机镇定的充分条件。利用Shur补理论，以线性矩阵不等式的形式给出了闭环系统的模式相关控制器。最后给出了一个数值算例，说明了该方法的有效性。
The modelling and stabilising control of networked control systems (NCSs) with stochastic packet loss and time-varying delays are addressed. In specific, a novel Markovian jump linear system with time-varying delays is used to model the NCS. Without using the augmented state method, sufficient conditions for the stochastic stabilisation of the NCS with packet loss and time-varying delays are obtained via the mode-dependent Lyapunov function method. The mode-dependent controller for the closed-loop NCS is presented in the linear matrix inequalities formulation via the Shur complement theory. A numerical example is given to illustrate the effectiveness of the proposed method.
