摘　　要：考虑一类只在传感器与控制器之间存在网络的多包传输网络控制系统,研究具有数据包错序、时延和丢包的多包传输网络控制系统的建模和稳定性问题.假设每个数据都带有状态标识符,通过在控制器前端引入一个存储器来储存数据,并在存储器内设置一个缓存区来解决乱序问题,将系统建模成不确定离散线性系统.然后利用Lyapunov方法推导出闭环系统渐近稳定的充分条件,并给出算例验证方法的可行性.Modeling and stability was studied for a class of networked control systems with multi-packet transmission only between sensors and controllers,and with time delay,data packet dropout and disorder.The disorder problem could be solved by assuming that each datum has a state identifier,introducing a memorizer in the front of controller to store data,and setting a buffer in the memorizer.By applying Lyapunov method,a sufficient condition of asymptotic stability for closed-loop systems was obtained.The simulation result in a numerical example showed that the approach was feasible.
