摘　　要：在动态控制中,控制器与执行器之间通信经常会出现数据延迟、丢包等现象。因此,为了保证动态控制的稳定性,减少网络传输中的丢包现象,本文基于动态矩阵设计了网络丢包控制系统。硬件部分设计滤波器、状态观测器,及输出反馈控制器。软件部分首先构建最优控制模型,基于动态矩阵分析网络丢包控制稳定性;其次输出反馈镇定控制,实现了网络丢包控制。进行系统测试,测试结果表明,设计的丢包控制系统性能良好,能有效减少网络丢包率,有一定的应用价值。In dynamic control,data delay and packet loss often occur in the communication between controller and actuator.Therefore,in order to ensure the stability of dynamic control and reduce packet loss in network transmission,a network packet loss control system is designed based on dynamic matrix.The hardware part designs filter,state observer and output feedback controller.In the software part,firstly,the optimal control model is constructed,and the stability of network packet loss control is analyzed based on dynamic matrix;Secondly,the output feedback stabilization control realizes the network packet loss control.The test results show that the designed packet loss control system has good performance,can effectively reduce the network packet loss rate,and has a certain Application value.
