Abstract :
In this paper, the threshold autoregressive modeling method is applied to build an accurate mathematical model for the time-delay from the controller to the actuator of NCS. A new time-delay compensation scheme is proposed based on this model. For this scheme, three networked controller design methods combined with the threshold autoregressive model to compensate the time-delay is discussed. At last, a simulation is demonstrated for this new time-delay compensation scheme.
