Research Interests
Our group is working on cooperative control and shared autonomy in robotic networks (Fujita Lab) and distributed energy management for energy efficient society (Hatanaka Lab). We are developing distributed optimization and learning algorithms for a variety of Cyber-Physical Systems. In particular, we study in an effort to work out fundamental principles to render highly-networked control systems totally optimal and/or robust state via distributed decision-makings.
