摘　　要：对广义网络控制系统进行建模与分析,针对传感器、控制器、执行器的驱动方式,以及系统是否存在脉冲分别建立数学模型.在建模的基础上,对一类具有短时延、传感器采用时钟驱动、控制器和执行器采用事件驱动的广义网络控制系统的因果性、能控性及能观性进行分析,给出了其具有因果性、能控、能观的充要条件.The modeling of singular networked control systems was discussed,and the mathematic models were developed for the different driven modes of sensors,controllers and actuators especially whether the impulse exists in the system.Then,the causality,controllability and observability were analyzed for a class of singular networked control systems with short time delay,where the sensors were clock-controlled while the controllers and actuators were both event-driven.The necessary and sufficient conditions were given for the causality,controllability and observability of singular networked control systems.
