网络控制系统的能控性和能观性

Controllability and observability of networked control systems

给出了网络控制系统的定义,并基于线性时不变系统的被控对象,建立了传感器为时钟驱动,控制器和作动器为事件驱动时长时滞网络控制系统的数学模型,对网络控制系统的均值能控、均方能控、均值能观及均方能观作了定义,得到了网络控制系统能控的充分或必要条件及能观的充要条件.

The mathematic model of networked control systems with long network-induced delay is set up based on the controlled process that is linear time-invariant system when the sensor is time driven, the controller and the actuator are event driven. The mean value controllability, mean square controllability, mean value observability and mean square observability of networked control systems are defined. The sufficient or necessary conditions for the controllability and the sufficient and necessary conditions for observability of networked control systems are presented.
