摘要:  Multidimensional (n-D)  systems refer to systems with dynamics depending on more than one independent  variables. During the past several decades, n-D  systems have drawn a lot of attention, and considerable research results have  been achieved, including modeling, stability, stabilization, filtering and  synthesis, etc. This is mainly due to the extensive practical and potential  applications of n-D  systems in various engineering fields, such as signal and image processing,  robust control of uncertain systems, learning control, medical applications,  wireless sensor networks, etc. Though the basic consideration of n-D(  n>2)system  theory can be often viewed as a generalization of the conventional 1-D system  theory, there exist deep and substantial differences between the 1-D case and  the n-D case, which make the analysis and synthesis of n-D systems much more  complicated and difficult than the 1-D case. This talk will give a brief  introduction to the n-D systems and the n-D system theory as well as its  applications, with an emphasis on the latest developments, accomplished  by the author and co-workers,  on several important topics such as the applications of computer algebra,  especially Grobner basis, in n-D system theory, the H-infinity control of n-D  systems, the multidimensional state-space realization and LFR (linear fractional  representation) uncertainty modeling.

个人简介：

Professor  Li XU received  the B. Eng. degree in Automatic Control from Huazhong University of Science and  Technology, Wuhan, China , in 1982, and the M. Eng. degree in  Information and Computer Sciences and the Dr. Eng. degree in System and  Information Engineering from Toyohashi University of Technology, Toyohashi, Japan , in March 1990 and March 1993,  respectively. From April 1993 to March 1998, he was an Assistant Professor at  the Department of Knowledge-Based Information Engineering of Toyohashi  University of Technology. From April 1998 to March 2000, he was a Lecturer at  the Department of Information Management, School of Business  Administration, Asahi  University, Gifu, Japan . Since April 2000, he has been  with Akita Prefectural University, Akita, Japan , where he is  currently a Full Professor at the Department  of Electronics and Information Systems. His research interests include  multidimensional system theory,  signal processing, and  the applications of computer algebra to control theory.  He has authored and co-authored more than 100 peer-reviewed journal and  proceedings papers. Professor  Xu has been an associate editor for the international journal of  Multidimensional Systems and Signal Processing (MSSP) since 2000, and was  a  guest co-editor for the special issue of “Applications of Grobner Bases in  Multidimensional Systems and Signal Processing” for MSSP published in  2001.
