Professor J. Lam received a BSc (1st Hons.) degree in Mechanical Engineering from the University of Manchester, MPhil and PhD degrees from the University of Cambridge. He is a recipient of the Outstanding Researcher Award of the University of Hong Kong and a Distinguished Visiting Fellow of the Royal Academy of Engineering. Prior to joining the Department of Mechanical Engineering, The University of Hong Kong, in 1993 where he is now Chair of Control Engineering, Professor Lam was lecturer at the City University of Hong Kong and the University of Melbourne.

Professor Lam is a Chartered Mathematician, Chartered Scientist, Chartered Engineer, Fellow of IEEE, Fellow of IET, Fellow of IMA, and Fellow of IMechE. He is Editor-in-Chief of IET Control Theory and Applications and Journal of The Franklin Institute, Subject Editor of Journal of Sound and Vibration, Editor of Asian Journal of Control, Associate Editor of Automatica, Proc. IMechE Part I: Journal of Systems and Control Engineering, International Journal of Systems Science, and three other SCI journals. His research interests include model reduction, robust control and filtering, delay systems, singular systems, positive systems, Markovian jump systems, multidimensional systems, networked control systems, vibration control, and complex networks.

报告内容: 
In this talk, an introduction to positive systems will be first provided. A characterization of the L1 performance in terms of linear inequalities is then given for positive linear systems which will be employed for the synthesis problem using static output feedback. An iterative linear programming algorithm is constructed for the computation of the output feedback gain. In particular, analytical solutions can be obtained for state-feedback control for the single-input case. An extension of the idea is also given to the multiple-input situation. A numerical example will be used for illustrating the methods and the results.
