Networked Control Systems have been the subject of extensive research over the last two decades. However, their development is still refrained through multifold design challenges. Indeed, interconnected subsystems make it hard to design local decision-making, whereas global design is typically undesired if not infeasible. The lack of formal guarantees is replaced in practice with heuristics built on human intuition and experience: a cornerstone rule of thumb is that allocating more resources leads to higher performance, or, broadly speaking, that “more is better”.In this talk, I will dig into, and possibly question, the role that such a common belief plays in the design of Networked Control Systems. I will consider three common design assumptions: (i)more sensors improve estimation quality; (ii) more communication links increase control performance; (iii) more collaboration enhances cooperative tasks. While these assumptions are reasonable in general, I will discuss three scenarios where they fail to capture the true nature of the system: (i) more sensors may hinder estimation under computational delays; (ii) more communication links may degrade control performance under communication constraints; (iii) more collaboration may be harmful in the presence of misbehaving agents. These considerations urge us to carefully (re-)think suitable design strategies, which are preliminarily investigated in the talk.
Luca Schenato received the Dr. Eng. degree in electrical engineering from the University of Padova in 1999 and the Ph.D. degree in Electrical Engineering and Computer Sciences from the UC Berkeley, in 2003. He held a post-doctoral position in 2004 and a visiting professor position in 2013-2014 at U.C. Berkeley. Currently he is Full Professor at the Information Engineering Department at the University of Padova. His interests include networked control systems, multi-agent systems, wireless sensor networks, distributed optimisation and synthetic biology. Luca Schenato has been awarded the 2004 Researchers Mobility Fellowship by the Italian Ministry of Education, University and Research (MIUR), the 2006 Eli Jury Award in U.C. Berkeley and the EUCA European Control Award in 2014, and IEEE Fellow in 2017. He served as Associate Editor for IEEE Trans. on Automatic Control from 2010 to 2014 and he is currently Senior Editor for IEEE Trans. on Control of Network Systems and Associate Editor for Automatica.
