This is of n o problem for SISO LTI systems since the phase response of such a system i s well defined.\n\nFor MIMO LTI systems\, this question becomes nontrivial since a good definition of matrix phase had not been available until rece ntly. In this talk\, we start with two definitions of matrix phase and pre sent two corresponding versions of the small phase theorem.\n\nOur current study shows that we can even extend the concept of phase and the small ph ase theorem to nonlinear systems and much beyond.\n\nProfessor Li Qiu\n\nD epartment of Electronic and Computer Engineering\n\nHong Kong University o f Science and Technology\n\nProf. Li Qiu received his Ph.D. degree in elec trical engineering from the University of Toronto in 1990. After briefly w orking in the Canadian Space Agency\, the Fields Institute for Research in Mathematical Sciences (Waterloo)\, and the Institute of Mathematics and i ts Applications (Minneapolis)\, he joined Hong Kong University of Science and Technology in 1993\, where he is now a Professor of Electronic and Com puter Engineering.\n\nProf. Qiu’s research interests include system\, co ntrol\, optimization theory\, and mathematics for information technology\, as well as their applications in manufacturing industry and energy system s. He is also interested in control education and coauthored an undergradu ate textbook “Introduction to Feedback Control” which was published by Prentice-Hall in 2009. He served as an associate editor of the IEEE Trans actions on Automatic Control and an associate editor of Automatica. He was the general chair of the 7th Asian Control Conference\, which was held in Hong Kong in 2009. He was a Distinguished Lecturer from 2007 to 2010 and was a member of the Board of Governors in 2012 and 2017 of the IEEE Contro l Systems Society. He is the founding chairperson of the Hong Kong Automat ic Control Association and a vice president of Asian Control Association. He is a Fellow of IEEE and a Fellow of IFAC.\n\nCo-sponsored by: Prof. Dr. Ryozo Nagamune / Dejan Kihas \n\nAgenda: \nGathering and Introduction\n\n Presentation\n\nQ&A\n\nRoom: CEME 2202\, Bldg: CEME (Civil and Mechanical Engineering Building)\, University of British Columbia\, Vancouver \, 6250 Applied Science Ln\, Vancouver\, BC V6T 1Z4\, Vancouver \, British Columb ia\, Canada\, Virtual: https://events.vtools.ieee.org/m/333239 LOCATION:Room: CEME 2202\, Bldg: CEME (Civil and Mechanical Engineering Bui lding)\, University of British Columbia\, Vancouver \, 6250 Applied Scienc e Ln\, Vancouver\, BC V6T 1Z4\, Vancouver \, British Columbia\, Canada\, V irtual: https://events.vtools.ieee.org/m/333239 ORGANIZER:nagamune@mech.ubc.ca SEQUENCE:12 SUMMARY:Talk and Webinar: Small Phase Theorem: versions 1.0 and 2.0 by Prof .
