New Smith Predictor and BPNN Control for Networked Control Systems

This paper aims at time-variant or uncertain network delay in the networked control systems (NCS), a novel approach is proposed that new Smith predictor combined with back propagation neural network (BPNN) control.Because this new Smith predictor doesnpsilat include network delay model, therefore network delay doesnpsilat need to be measured, identified or estimated on-line, it is applicable to some occasions that network delay is random, timevariantor uncertain in the NCS. Based on CSMA/AMP (CAN bus), the results of simulation show validity of the control scheme.
