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 it is no need to measure, identify or estimate network delays on line. Based on IEEE 802.11 b/g (WLAN), the results of simulation show validity of this control scheme, indicate that system has better dynamic performance and anti-jamming ability.
