报告人简介:Dr. Fen Wu received the B.S. and M.S. degrees in automatic control from the Beijing University of Aeronautics and Astronautics, Beijing, China, in 1985 and 1988, respectively, and the Ph.D. degree in mechanical engineering from the University of California at Berkeley, Berkeley, CA, USA, in 1995.

From 1995 to 1997, he was a Research Associate with the Centre for Process Systems Engineering, Imperial College of Science, Technology and Medicine, London, U.K. He was a Staff Engineer with Dynacs Engineering Company Inc., Houston, TX, USA, on the International Space Station plant/controller interaction analysis project from 1997 to 1999. He is currently a Professor with the Mechanical and Aerospace Engineering Department, North Carolina State University, Raleigh, NC, USA. He has authored over 150 conference papers and journal articles. His current research interests include linear parameter-varying and switching control of nonlinear systems, robust control subject to physical constraints, nonlinear control using sum-of-square (SOS) programming, and the application of advanced control and optimization techniques to aerospace, mechanical, and chemical engineering problems. His research has been sponsored by NSF and NASA.

Dr. Wu has been elected to ASME Fellow in 2015 and AIAA Associate Fellow in 2008. He served as Associate Editors for ASME Journal of Dynamic Systems, Meassurement and Control, IEEE Transactions on Automatic Control, and Automatica.
