Cyber-Attack Detection with Fault Accommodation Based on Intelligent Generalized Predictive Control

Abstract

The Generalized Predictive Control (GPC) is a favored controller implementation method in the Networked Control System (NCS). This paper proposes an Intelligent Generalized Predictive Controller (IGPC) as an enhancement for the standard GPC. The IGPC is designed with fault-tolerant capabilities and cyber-attacks detection. Because of the used fault accommodation technique, the proposed cyber-attacks detector is able to clearly detect the presence of attacker control signal and to distinguish between the effects of the attacker signal and fault in the plant side. The test result of the proposed method shows that it can be significantly used for detection of the cyber-attack.
