【摘要】：研究存在传感器-控制器之间数据丢包的长时延网络控制系统(NCSs)的容错控制问题。考虑在随机外界扰动的基础上,进行传感器发生任意失效故障时NCSs容错控制器的设计。引入一类具有随机性的开关矩阵,建立带有随机外界扰动向量的丢包长时延NCSs的增广模型。结合H!控制理论,构造适当的Lyapunov函数,通过求解矩阵不等式得到状态反馈控制器,并给出系统满足渐近稳定性的充分条件。仿真算例验证了结论的可行性及有效性。
[Abstract]:The problem of fault-tolerant control for long delay networked control systems with packet loss between sensors and controllers is studied. The NCSs fault-tolerant controller is designed in the event of arbitrary failure of the sensor. A random switching matrix is introduced to establish the extended model of the long-delay NCSs with random external disturbance vector. The theory of control, the construction of proper Lyapunov function, and the solution of matrix inequality are used to obtain the state feedback controller, and the sufficient conditions for the system to satisfy the asymptotic stability are given. The simulation example verifies the feasibility and validity of the conclusion.
