Abstract
In a networked control system in which the controller and actuators are connected directly,the sampling signal is read out periodically from the buffers set in the actuator.The signal is optimally used to calculate the control parameters,therefore,the network-delay is decreased.Further,by means of the state equation and observation,a method to compensate the delay is proposed here.(Simulation) results verify its effectiveness.
