Networked Constrained Cyber-Physical Systems subject to malicious attacks: a resilient set-theoretic control approach
This work addresses the need for resilient control in safety-critical cyber-physical systems under communication channel attacks.
The paper presents a set-theoretic control framework for networked constrained cyber-physical systems that uses physical watermarking to detect and mitigate cyber attacks, ensuring uniformly ultimate boundedness and constraint satisfaction. Simulations demonstrate effectiveness against Denial of Service and False Data Injection attacks.
In this paper a novel set-theoretic control framework for Networked Constrained Cyber-Physical Systems is presented. By resorting to set-theoretic ideas and the physical watermarking concept, an anomaly detector module and a control remediation strategy are formally derived with the aim to contrast severe cyber attacks affecting the communication channels. The resulting scheme ensures Uniformly Ultimate Boundedness and constraints fulfillment regardless of any admissible attack scenario. Simulation results show the effectiveness of the proposed strategy both against Denial of Service and False Data Injection attacks.
