There are a lot of large-scale dynamical systems that can be regarded as hierarchically networked multi-agent systems in a variety of fields including control.  One of the ideas to properly handle those systems is "Glocal (Global/Local) Control," which was proposed as a new direction of control towards smart cities. Glocal control means that the global purpose is achieved by local actions of measurement and control cooperatively, and the key for the realization is hierarchically networked dynamical systems with multiple resolutions in time and space depending on the layer. In the first part of the talk, the background, the idea, and the concept of glocal control are addressed based on an understanding of Internet of Things (IoT) from the control perspective. The second part is concerned with analysis and synthesis for hierarchically decentralized control for networked dynamical systems.  We propose a new theoretical framework that can take account of the tradeoff between the global and local objectives to achieve the desired harmony under change of the environments. Several new ideas, by exploiting the special structure of the target systems, enable us to develop scalable control design methods based on the powerful theory in classical, modern, and robust control. The effectiveness of the new theoretical foundations on the analysis and synthesis is experimentally confirmed by applications to electric vehicle control.  Applications to three different fields, namely synthetic biology, electrical networks, and urban traffic networks, are presented in the last part of the talk.

Dr. Hara has received many awards in control including the George S. Axelby Outstanding Paper Award from the IEEE Control System Society in 2006. He was the President of SICE (Society of Instrument and Control Engineers, Japan) in 2009, a Vice President of the IEEE Control Systems Society in 2009 to 2010, and an IFAC Council member from 2011 to 2017. He is a Fellow of IFAC, IEEE, and SICE.
