Delay-loss Estimation and Control for Networked Control Systems Based on Hidden Markov Models

Abstract

Both the delay and loss information are used to build the hidden Markov model (HMM) for the networked control system. The validity of the model is evaluated. Based on the model, delay and packet-loss are estimated. A close-loop control experiment over campus network is designed to verify the method. The results show the validity of the hidden Markov model
