V. COMPENSATION FOR SENSOR-TO-CONTROLLER DELAY
The network-induced delays have two parts: sensor-tocontroller
delay sc τ and controller-to-actuator delay ca τ .
Because the plant state estimates the controller node gets each
sampling period are the estimates sampled sc τ ago, the
performance of the system will become bad if these estimates
are used as feedback vector directly. But if the delay sc τ can be
known before the computation of the control signal, we can use
the observer to rebuild the nondelayed plant estimates, which
are more accurate for the controller to generate control signal.
The task of observer to compensate for the delay sc τ can be
realized with the help of synchronous communication
