GAO Huijun

Huijun Gao was born in Heilongjiang Province, China, in 1976. He received the Ph.D. degree in control science and engineering from Harbin Institute of Technology (HIT), Harbin, China, in 2005. He is currently a full-time professor with School of Astronautics, HIT, director of Research Institute of Intelligent Control and Systems, HIT, and Chairman of HIT Youth Association for Science & Technology. He is also a committee member of All-China Youth Federation.

His main research interests include robust filtering, networked control and their applications in industry and aerospace engineering, and in these areas, his research findings have been published in top international journals including IEEE Transaction on Automatic Control, Automatica etc. He has published more than 100 international journal papers, of which, more than 40 are published in the series of IEEE Transactions (including 28 regular papers). His scientific papers have been cited for more than 2000 times. Currently, he is an Associate Editor for more than 10 international journals including Automatica, IEEE Transactions on Control Systems Technology and so on.

He was a recipient of the National Outstanding Youth Science Fund in 2008. He also received several academic and teaching awards, including the National Outstanding Doctoral Thesis Award, the National Natural Science Award of China, the Provincial Natural Science Award of Heilongjiang, the SCOPUS Young Researcher Award, the University of Alberta Dorothy J. Killam Memorial Postdoctoral Fellow Prize, the Special Government Allowance of Heilongjiang, the Outstanding Teacher Award of Heilongjiang, and so on. In 2011, he won the China Youth May 4th Medal, the National Award for Youth in Science and Technology, and the Tan Kah Kee Young Scientist Award. Prof. Gao is an Honorary Professor at the University of Hong Kong.

Analysis and Synthesis of Dynamic Systems in Networked Environment

Communication network not only leads to great revolution for control systems, but also brings challenges to traditional control theory. Hence, the problem of analysis and synthesis of dynamic systems in networked environment has been one of the research hotspots in international academic areas and industry fields. In the context of many engineering projects such as networked complex production and manufacture processes, aerospace vehicle control, this project investigates the problems of time-varying transmission delay, random package dropout, data misorder, quantization and coding-and-decoding error that are caused by communication network, and establishes a unified mathematical model that incorporates communication parameters for networked dynamic systems. New stability criteria for time-delay systems with multiple delay components, convex optimization design algorithms for state- and output-feedback controllers, and state estimation and fault detection strategies are proposed for systems with network communications. This project sets up a unified theoretical framework for modeling, control, estimation and fault detection of dynamic systems in networked environment.
