Analysis on network-induced delays in networked learning based control systems

Abstract

Local controller and remote learning device are connected through communication network in Networked Learning based Control Systems (NLCSs). Network-induced delays are inevitable during data transmission, and will deteriorate the real-time transmission of learning result from learning device to controller and even destabilize the entire system. This paper deals with the delays in NLCSs. The sources of delays are discussed and the possibility of reducing all delays into an equivalent delay is proposed. Finally, experimental measurements for that equivalent delay on Ethernet are conducted. © Springer-Verlag 2004.
