Title: Cyber-physical Energy Systems for the Energy Revolution

Networking, intelligence and integration of cyber and physical systems are the trend of information science and technology development. Cyber-physical systems is the foundation of the energy revolution and technology revolution with tremendous challenges on cyber-physical modeling, intelligence design, system optimization and control. Cyber-physical energy systems with hydrogen storage offers a possible solution for energy supply and consumption without carbon emission and pollution, and would lead to the energy revolution towards resolving the global warming issue. It is shown that with the nontraditional energy storage technology the hydrogen enabled zero-carbon intelligent energy system provides an ideal infrastructure for energy supply and consumption without carbon emission and pollution, and would lead to the energy revolution towards resolving the global warming issue.

Title: Cyber-physical systems: Analysis and Design

Cyber-physical systems (CPS), such as smart grids and intelligent transportation systems, are complex systems where software and hardware components are seamlessly integrated toward performing well-defined tasks. However, this integration increases the vulnerability of CPS with higher possibility of cyber-attack that could cause severe consequences to economics, society, and human beings. Hence, cyber-security is critical and important in CPS. In this talk, the security of CPS is discussed from the perspectives of attackers. We will introduce the background of CPS and security issues, and some existing work on cyber-attacks. We then present our recent work on the design of stealthy hybrid attacks to CPS, which enables attackers to launch hybrid cyber-attacks more effectively to maximize system performance degradation with less chance to be detected.

Title: Glocal (Global/Local) Control for Hierarchical Cyber Physical Systems: Theoretical Foundation towards Practical Applications

There are a lot of world-wide crucial issues to be solved such as energy, environments, and transportations. Current and future directions of science and technology in almost all fields including control should be contributed for realizing desirable societies, say smart cities. This means that our target systems in control are large-scale cyber physical systems with hierarchical structure. One of the ideas to properly handle such systems is "Glocal (Global/Local) Control," which means that the global objective is achieved mainly by local actions of measurement and control cooperatively. This is a new control framework for realizing smart cities. The key for developing a fundamental theory is hierarchically networked dynamical systems with multiple resolutions in time and space, and one of the most important issues is how to compromise the global and local control objectives.

The main purpose of this talk is to show that new ideas, by exploiting the special structure of the target networked systems, with utilization of powerful existing theory in classical, modern, and robust control enable us to develop scalable methods for control analysis and design. The effectiveness of the proposed methods is verified through practical applications including glocal control for a type of electric vehicles with multiple controllable wheels. After explanations of the background, the idea, and the concept of glocal control, the first part is focused on the analysis, where stability and robust stability conditions are provided for hierarchically decentralized control systems. The second part is devoted to hierarchical optimal control based on the standard LQ optimal control, which gives a systematic way of compromising the global and local objectives. In the third part, a fairly general framework for compromising the global and local achievable performances based on a novel setting in the standard robust control. The effectiveness of all the proposed methods is verified through practical applications including glocal control for a type of electric vehicle with multiple motor driven wheels. Some remarks on the future research directions are addressed at the end of the talk.
