Resilient control in cyber-physical systems

Cyber-Physical Systems (CPS), the amalgamation of sophisticated sensing, communication, and computing technologies, applied to physical spaces, have become intrinsically linked to society’s critical infrastructures. Indeed, CPS find applications in energy delivery systems, intelligent transportation, smart buildings and health care. Within these systems, technological advances have enabled mankind to improve their ability to both accurately monitor large scale systems and precisely manipulate their behavior in order to achieve complex local and global objectives. Nonetheless, the opportunities created by CPS are met with significant burdens and challenges, threatening the resilience of these systems to both benign failures and malicious attacks. In this monograph, we provide a comprehensive survey of intelligent tools for analysis and design that take fundamental steps towards achieving resilient operation in CPS. Here, we investigate the challenges of achieving reliable control and estimation over networks, particularly in the face of uncertainty and resource constraints. Additionally, we examine the threat of bad actors, formulating realistic models to characterize adversaries as well as systematic tools to detect and respond to attacks. Finally, we include a brief introduction to the problem of privacy in CPS, providing both measures to describe and techniques to preserve the confidentiality of sensitive information.
