Intelligent Generalized Predictive Control strategy for Networked Control System with an internal cyber-attack detector

Abstract

The Generalized Predictive Controller (GPC) is a preferred controller implementation method in the Networked Control System (NCS). However, the prediction feature of the standard GPC weakens the ability for fast detection of cyber-attack on the remote plant side. This paper proposes an Intelligent Generalized Predictive Controller (IGPC) as an enhancement for the standard GPC. The IGPC is designed along with an internal cyber-attack detector; this one is based on the comparison between the predicted and actual nonlinear terms of the plant by a specific computation algorithm. The test result of the proposed method shows that it can be significantly used for detection of the cyber-attack.
