Wireless Networked Control Systems with Nonlinear Control and Novel Smith Predictor

This paper aims to the random and uncertain network delays, as well as controlled plant might be time-variant or nonlinear, a novel approach is proposed that novel Smith predictor combined with nonlinear control for wireless networked control systems (WNCS). This novel Smith predictor comes true to hide predictor models of the network delays into real network data transmission processes, therefore network delays don’t need to be measured, identified or estimated on-line. Based on IEEE 802.15.4 (ZigBee), the results of simulation show validity of this control scheme, and indicate that system has better dynamic performance and anti-jamming ability.
