Observer Design for Detection of Attack Patterns in Cyber-Physical Systems

Abstract

This article focuses on the design of a Luenberger structure observer with residual generation for the detection of different attack schemes (Denial of Service (DoS) and False Data Injection (FDI)) targeting the sensors and actuators of a discrete cyber-physical system. To simulate a more realistic attack signal, Markovian distribution logic is used to simulate the behavior of the signals. To demonstrate the effectiveness of the proposed scheme, a system of three interconnected tanks is used.
