title = "Robust disturbance attenuation of nonlinear systems using output feedback and state-dependent scaling",
abstract = "This paper presents an approach to output feedback stabilization with script L sign2 disturbance attenuation for nonlinear systems in the presence of dynamic uncertainties. A new formulation of state-dependent scaling is introduced into the output feedback design, which unifies treatment of nonlinear and linear gains. The effect of disturbance on the controlled output, which is allowed to be any function of output measurements, can be always attenuated to an arbitrarily small level with global asymptotic stability if the plant belongs to a wide class of triangular systems whose uncertainties do not necessarily have finite linear-gains. The uncertain dynamics is not limited to input-to-state stable systems either. The approach is not only a natural extension of popular approaches in robust linear control, but also advantageous to numerical computation which is applicable to non-triangular systems as well as triangular systems.",

note = "Funding Information: Dr. Jiang received the B.Sc. degree in mathematics from the University of Wuhan, Wuhan, China, in 1988, the M.Sc. degree in statistics from the Universit{\`e} de Paris-sud, Paris, France, in 1989, and the Ph.D. degree in automatic control and mathematics from the {\`E}cole des Mines de Paris, Paris, France, in 1993. From 1993 to 1998, he held visiting researcher positions in several institutions including INRIA (Sophia-Antipolis), France, the Department of Systems Engineering in the Australian National University, Canberra and the Department of Electrical Engineering in the University of Sydney. In 1998, he also visited several U.S. universities. In January 1999, he joined the Polytechnic University at Brooklyn as an Assistant Professor of Electrical Engineering, where he has been an Associate Professor since 2002. His main research interests include stability theory, optimization, robust and adaptive nonlinear control, with special emphasis on applications to underactuated mechanical systems, communication and biological networks. He has authored or coauthored four book chapters and over 100 scientific papers in peer-reviewed international journals and conferences. Currently, He is a Subject Editor for the International Journal of Robust and Nonlinear Control , Associate Editor for Systems & Control Letters and IEEE Transactions on Automatic Control . He served as an Associate Editor of the IEEE CSS Conference Editorial Board during 2000–2002. He is the recipient of a prestigious Queen Elizabeth II Felloship Award (1998) from the Australian Research Council and a CAREER Award (2000) from the U.S. National Science Foundation. He is recently appointed as an Othmer Junior Fellow at the Othmer Institute for Interdisciplinary Studies, Polytechnic University. Funding Information: The work of Z.-P. Jiang is supported in part by NSF Grant ECS-0093176. ",
