Fuzzy Neural Network-based Time Delay Prediction for Networked Control Systems

Abstract

In networked control systems, the varying transmission time delay of the transmitting signal is unavoidable. If the varying transmission time delay exceeds the fixed sampling time, the system will be uns table. To solve this problem, in this paper, the logic- based fuzzy neural networks are applied to the prediction of transmission time delay. The predicted time delay is used as a sampling period of the networked control systems. To show the usability of the proposed method, the transmission time delay data are collected from the real system, and these collected data are used to train and test the logic-based fuzzy neural networks.
