讲座题目:High Assurance Autonomy for Cyber-Physical Systems:Secure Control Analysis and Design

讲座内容:Security of Cyber-Physical Systems (CPS) against malicious cyberattacks is an important yet challenging problem. Since most cyberattacks happen in erratic ways, it is usually intractable to describe and diagnose them systematically. Motivated by such difficulties, this work presents a set of theories and algorithms for a cyber-secure control architecture for the CPS from the control theoretic perspective. Our efforts are divided in two folds: 1) we first investigate the detectability of cyberattacks from the system’s behavior under cyberattacks. Specifically, we conduct a study on vulnerabilities in the CPS’s monitoring system against the stealthy cyberattack that is carefully designed to avoid being detected by its detection scheme; and 2) a cyber-secure control strategy for CPS that are robust to various types of cyberattacks is developed. While most existing studies have investigated secure control by assuming specific attack strategies, in this research we propose a robust hybrid control scheme which can be secure to a wide range of cyberattacks. The proposed cyber secure controller is composed of multiple sub-controllers, each matched to a different type of cyberattack. A CPS using this control scheme is able to adapt its behavior to various cyberattacks by switching sub-controllers to achieve the best performance. The proposed analysis and control methods are demonstrated with illustrative examples on Unmanned Aerial System (UAS) applications.
