Abstract :
This paper aims to the time-variant, random and uncertain wireless network delay, a novel approach is proposed that new Smith predictor combined with the CMAC-PID control for the wireless networked control systems (WNCS). This new Smith predictor does not include the prediction models of the network delays, therefore network delays are no need to be measured, identified or estimated on line. It is applicable to some occasions that the network delays are larger than one, even tens of sampling periods. Based on IEEE 802.15.4 (ZigBee), the results of simulation experiment show validity of this control scheme, indicate that system has better dynamic performance and anti-jamming ability.
