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.

Prof. Daniel W. C. Ho received BSc, MSc and PhD degrees in mathematics from the University of Salford (UK) in 1980, 1982 and 1986 respectively. From 1985 to 1988, he was a Research Fellow in Industrial Control Unit, University of Strathclyde (Glasgow, Scotland). In 1989, he joined the Department of Mathematics, City University of Hong Kong. Currently, he is the Chair Professor and Assistant Dean in Teaching Innovations of College of Science and Engineering. Prof. Ho serves as Subject editor for  Journal of the Franklin Institute, Associate Editor for five other international Control journals including IET Control Theory and its applications, and Asian Journal of Control.  He is recipient of “The Best paper award” from the 8th Asian Control Conference. In 2012, he is honored to be the Chang Jiang Chair Professor, Nanjing University of Science and Technology, awarded by Ministry of Education, China. Recently, he has been named in the list of Highly Cited Researchers published by Thomson Reuters in 2014 and 2015.
