摘要
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.
The stabilization problem for networked control systems（NCS） with random packet dropouts is studied in this paper.Both sensor-to-controller（S/C） and controller-to-actuator（C/A） packet dropouts are considered,which are modeled respectively.Based on Lyapunov stability theory,sufficient condition is derived,which ensures the globally mean-square asymptotically stability for the closed-loop systems.Moreover,the gain matrix of the state feedback control law is obtained by using the linear matrix inequality（LMI） approach.Numerical examples illustrate the effectiveness of the results.
