Research Interests
Our group is working on:

  • Distributed Energy Management for Energy Efficient Society (Hatanaka Lab)
  • Cooperative Control of Robotic Network (Fujita Lab)

We are developing distributed optimization and learning algorithms for a variety of Cyber-Physical Systems including buildings, data centers, microgrids and robotic networks to realize energy-efficient and resilient society. 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.
