研究具有随机丢包的网络控制系统(NCS)的镇定问题.同时考虑传感器节点到控制器节点(S/C)和控制器节点到执行器节点(C/A)的随机丢包,并分别对这两种丢包现象建模.基于Lyapunov稳定性理论,得到闭环系统全局均方渐近稳定的充分条件.进一步利用线性矩阵不等式(LMI)方法,得到状态反馈控制律的增益矩阵.数值仿真算例验证了所得结果的有效性.
In this paper, we study the stabilization problem of network control system (NCS) with random packet loss and consider the random packet loss from sensor node to controller node (S / C) and controller node to actuator node (C / A) Based on the Lyapunov stability theory, the sufficient conditions for the global mean square asymptotic stability of the closed-loop system are obtained. The gain matrix of the state feedback control law is further obtained by using the linear matrix inequality (LMI) method. The results verify the validity of the results obtained.
