Outline of Final Research Achievements

A cyber-physical system (CPS) is a system in which a physical system and an information system are interconnected. It is possible to construct a high-performance control system that utilizes the computational power of information systems. A CPS has a wide range of applications such as electric power, medical care, and transportation. Furthermore, in a society where many devices are connected via the Internet, there is an increasing need for control methods that take into account external attacks. Therefore, in this research, we focus on the control / verification method for constructing a secure CPS. Specifically, I worked on the following three points. (1) Distributed event-driven control, (2) Cyber attack detection in power networks, (3) Distributed optimization of energy management systems using blockchain.
