| 摘 要： | 针对任意丢包和马尔可夫丢包两种有界丢包情况,考虑了系统元件发生故障时网络化控制系统可靠保成本控制问题。提出了一种新的把传感器与执行器同时发生故障的情况考虑在内的故障描述方法,利用丢包依赖的李亚普诺夫方法,得到了可靠控制器存在的充分条件,通过求解具有线性不等式约束的凸优化问题,得到最优可靠控制器增益的参数表达式,它使得系统在有界丢包与元件故障情况下保持渐近稳定,同时使系统性能指标达到最优。数值仿真验证了方法的有效性。

| Abstract: | Concerning with the reliable guaranteed cost control problem for networked control systems(NCSs) with packet dropouts and component failures,two kinds of packet-dropout processes are investigated: the arbitrary packet-dropout process and the Markovian packet-dropout process.A new failure model enables us to take sensor and actuator failures into consideration simultaneously.By using packet-dropout dependent Lyapunov approach,a sufficient condition for the existence of reliable guaranteed cost controller is ... |
