To aim at time-variant or random network delay in the Wireless Networked Control Systems (WNCS), as well as controlled plant might be uncertain, a novel approach is proposed that new Smith predictor combined with Fuzzy Radial Basis Function Neural Network (FRBFNN). Because new Smith dynamic predictor hides predictor model of the network delay into real transmission process of the network data, further the network delay no longer need to be measured, identified or estimated on-line. Therefore it is applicable to some occasions that network delay is the random, time-variant or uncertain, possibly large compared to one, even tens sampling periods, meanwhile, there are some data dropouts in closed loop.
