Abstract

In this paper, a novel approach is proposed to deal with network delay, based on new Smith predictor combined with generalized predictive control (GPC) for wireless networked control systems (WNCS). Because new Smith dynamic predictor hides predictor model of the network delay into real data transmission process, further the network delay no longer need to be measured, identified or estimated on-line. Based on IEEE 802.15.4 (ZigBee), simulation results are given to illustrate the effectiveness of the method.
