摘　　要：针对网络诱导时延大于一个采样周期的网络控制系统，本文提出了一种基于Mrkov延迟特性的建模方法，并利用Markov线性跳变理论，给出了闭环系统的稳定性条件，同时基于LMI形式给出了相应的控制器设计方法。仿真结果验证了本文所提方法的正确性和有效性。Aiming at the network-induced time delay is more than the sample period in networked control system （NCS）, a novel modehng method based on the Markov delay characteristic is proposed in this paper.Utilizing the Markov linear jump theory, the stabilizability con- dition is given for the closed-loop system, and the corresponding controller design method is presented in the LMI form.The simulation results show the correctness and effectiveness of the proposed method.
