| Abstract: | 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. |
