摘　　要：在保证稳定性的前提下,研究具有数据包丢失的网络控制系统主动容错控制问题.基于一类包含马尔可夫丢包过程的网络控制系统模型,考虑了执行器可能失效的情况.利用Lyapunov稳定性理论和线性矩阵不等式方法,获得了系统的保性能被动容错控制器.从控制性能的角度考虑,针对不同的执行器失效模式,得到了丢包网络环境下系统的主动容错控制器的设计方法.数值示例表明,该控制器设计方法是有效的.The problem of active fault-tolerant control for networked control system with packet dropout is addressed with stability guaranteed. Based on a model of networked control system with the effects of Markovian packet dropout process, the failures of actuators are considered. The Lyapunov stability theory and the linear matrix inequality method are employed to derive the guaranteed cost passive fault-tolerant controller for the system. Furthermore, the design procedure of the active fault-tolerant controller for network with packet dropout is proposed for different actuator failure model with consideration of control performance. The numerical example shows the effectiveness of the proposed method for networked control system.
