From Feb. 11 to Feb. 19, prof. Daniel Zelazo, from the Faculty of Aerospace Engineering (more information can be found in https://zelazo.net.technion.ac.il ), Technion-Israel Institute of Technology, visited CDSL. Taking lessons from his two seminars and further discussions with the members, it was a fruitful time to share the viewpoints and experiences on various topics of researches.
At Feb. 12, he made a tutorial on graph theory in systems and controls. The topic of the seminar began with basic definitions and properties of protocols on graphs, but was smoothly continued to specific and detailed topics of structural stability and input-output properties of networked control systems. For example, the concept of “stability of graphs” described in the figure can be used for the analysis of structural stability of networked systems.
At Feb. 14, he made the second seminar and took up the main subject of passivity, monotonicity, and network optimization, which he addressed as a new framework for the analysis of networked control systems. The lesson of the talk included necessary and sufficient conditions for a network of passive dynamical systems to reach an output agreement and connections between notions of duality in static optimization to cooperative control.
The lessons were impressive to us, and they left a new point of view as well as several research items to be thought; such as the combination of “blended dynamics,” and “maximal equilibrium passivity”.
