摘要
针对切换广义被控对象的网络控制系统,根据网络的时延特性,结合被控对象为广义切换系统的特点,在传感器采用时间驱动,控制器和执行器采用事件驱动,网络诱导时延小于一个采样周期时进行系统建模,然后通过构造李雅普诺夫函数和多李雅普诺夫函数的方法研究了系统的稳定性,并设计了保证时延切换广义网络控制系统渐近稳定的鲁棒状态反馈控制器.
The switched singular networked control systems with time-delay are considered, and the modeling problem is discussed. Supposing that the sensor node is time-driven, the controller and executor are event-driven, and the network-induced delay is less than one sampling period, the system can be modeled as a linear discrete switched system with delay. By the construction of Lyapunov function and multiple Lyapunov functions, the stability of the system can easily be assessed. Meanwhile, the robust asymptotic stabilizing state feedback control law is proposed for the switched singular networked control system.
