Title: Distributed Networked System under Communication Information Constraints
Abstract: A distributed network system (DNS) consists of a large number of small, inexpensive agents deployed over a vast region, in which each agent is capable of collecting, processing information and communication with neighboring agents. Node collaboration is the key for the success of DNSs due to the fact that each node itself is limited by communication range, power, and processing ability.
An interesting aspect of the dynamics in DNSs is that certain types of globally collective behavior emerge from local interactions among the nodes. Consensus in DNSs requires the integration of the stability, control, filtering and sensing aspects of the information processing and computational analysis.
In this talk, we shall present some recent work on the consensus performance of DNS under network induced imperfect communication. These constraints include partial-information transmission, packet loss, time-delay and quantization. In addition, this talk will also discuss some recent investigation on the event-triggered data transmission in discrete-time multi-agent consensus problem with communication delays.
Daniel W. C. Ho received the B.Sc., M.Sc., and Ph.D. degrees in mathematics from the University of Salford, Greater Manchester, U.K., in 1980, 1982, and 1986, respectively.
From 1985 to 1988, he was a Research Fellow with the Industrial Control Unit, University of Strathclyde, Glasgow, U.K. He is currently a Chair Professor in applied mathematics with the Department of Mathematics, and the Assistant Dean (Teaching Innovations) with the College of Science and Engineering, City University of Hong Kong, Hong Kong which he joined in 1989. His current research interests include control and estimation theory, complex dynamical distributed networks, multi-agent networks, and stochastic systems. He has over 200 publications in scientific journals.
Prof. Ho is a Fellow of the IEEE. He was honored to be the Chang Jiang Chair Professor awarded by the Ministry of Education, China, in 2012. He has been on the editorial board of a number of journals including IEEE Transactions on Neural Networks and Learning Systems, IET Control Theory and its Applications, Journal of the Franklin Institute and Asian Journal of Control. He is named as ISI Highly Cited Researchers (2014-2016) in Engineering by Thomson Reuters.
