用于在无线网络控制系统（WNCSs）的组件之间传递信息的通信信道会由于时变衰落和干扰而遭受分组丢失。具有丢失数据包的WNCS可以建模为具有单时间步延迟模式观测的马尔可夫跳变线性系统。虽然这样的系统的最优线性二次调节问题已经解决，我们得到的必要和充分条件的稳定性。我们还表明，与一个例子，考虑一个通信信道模型的基础上WirelessHART（市场上的无线通信标准，专门设计用于过程自动化），这样的条件是必不可少的分析WNCS的数据包丢失建模与伯努利随机变量表示的预期值的真实的随机过程中的信道。
The communication channels used to convey information between the components of wireless networked control systems (WNCSs) are subject to packet losses due to time-varying fading and interference. The WNCSs with missing packets can be modeled as Markov jump linear systems with one time-step delayed mode observations. While the problem of the optimal linear quadratic regulation for such systems has been already solved, we derive the necessary and sufficient conditions for stabilizability. We also show, with an example considering a communication channel model based on WirelessHART (a on-the-market wireless communication standard specifically designed for process automation), that such conditions are essential to the analysis of WNCSs where packet losses are modeled with Bernoulli random variables representing the expected value of the real random process governing the channel.
