摘要 为了研究具有长时延和丢包的网络控制系统保性能控制问题,假设传感器由时钟驱动,控制器和执行器由事件驱动,网络时延在两个采样周期之间,丢包具有马尔科夫跳变特性,利用状态增广的方法,把具有长时延和丢包的网络控制系统建模为具有两种运行模式的离散时间马尔可夫跳变系统,把网络时延转化为系统参数矩阵的不确定性。在此基础上,利用马尔可夫线性跳变系统理论和线性矩阵不等式方法,推导出使网络控制系统随机稳定的保性能控制律存在的充分条件,并给出了设计方法。数例仿真说明了所用方法的有效性。 In order to research the guaranteed cost control of networked control system, the system model is established as Markovian jump linear system with two running modes through state augmentation technique. The condition for the existence of the guaranteed con- trol law is derived by means of Markovian jump liner system theory and LMI method. The design method for guaranteed controller is also presented. Finally, a numerical example is employed to demonstrate the validity of the method.
