Intelligent control systems are pervasive in modern critical infrastructures such as power grids, transportation systems, healthcare informatics, etc. The system level integration of cyber and physical components has made control systems vulnerable to malicious events and cyber attacks. Distinct from traditional measures of robustness and reliability, security and resilience are important system attributes of control systems that are often subject to exogenous disturbances and exposed to unexpected adversarial attacks or events. Hence there is need for fundamental understanding of these concepts in the context of control systems, which can lead to a new set of computational and system design tools.
Game theory is a versatile quantitative tool and has been used to model different types of interactions among players or subsystems at multiple layers of the system. It was first used in economics to understand the outcome of strategic behaviors of players who make rational decisions. In control theory, game theory has successfully been used to design robust controllers for dynamical systems that are subject to uncertainties. Recently, game theory has been used as a quantitative method for analyzing network security polices and designing defense mechanisms. The wide application domains of game theory have made it a unifying framework for a holistic and fundamental understanding of cyber-physical systems.
The full-day workshop aims to address security and resilience aspects of control systems using decision and game-theoretic methods. The workshop will consist of topics covering different aspects of resilient control systems including secure communications, network security, control system management, resilient control design and human factors. The workshop will also draw examples from power systems and smart grid to illustrate various applications of game theory.
