摘　　要：针对广义网络控制系统,该文研究了其同时具有测量和控制数据丢失的问题。首先把广义系统进行等价变换使其变为正常系统。然后采用满足Bernoulli分布的随机变量来描述多测量和多控制数据包的随机丢失问题。设计的输出反馈控制器使得闭环系统渐近稳定且满足给定的性能约束。利用矩阵不等式方法给出了动态输出反馈控制器存在的充分条件。采用改进的CCLM算法给出了输出反馈控制器设计参数的求解方法。最后数值例子表明了所提设计方法的有效性。In this paper,the control with both multiple measurement and control packets dropouts for descriptor systems is investigated.Firstly,the descriptor systems are transferred to the normal systems.Then two independent Bernoulli distributed white sequence are used to describe the multiple measurement and control packet dropouts.An output controller is designed to make the systems stable and achieve the prescribed disturbance attenuation level.A sufficient condition for the existence of the dynamic output feedback controller is presented via matrix inequalities.The extended CCLM algorithm is applied to solve the parameters of the controller.Finally,an example is provided to illustrate the usefulness of the design method.
