Abstract:  Low gain feedback refers to a family of stabilizing state feedback gains that are parameterized in a scalar, referred to as the low gain parameter, and go to zero as the low gain parameter decreases to zero. Low gain feedback was initially proposed to achieve semi-global stabilization of linear systems subject to input saturation, and later found its other applications, including stabilization of linear systems in the stabilization in the presence of input delays. In this talk, we discuss the concept of low gain feedback, its properties, its design methods, and its applications in semi-global stabilization of linear systems subject to input saturation and stabilization of linear systems in the presence of input delay.

Bio:  Zongli Lin is the Ferman W. Perry Professor in the School of Engineering and Applied Science and a Professor of Electrical and Computer Engineering at the University of Virginia. He received his B.S. degree in mathematics and computer science from Xiamen University, Xiamen, China, in 1983, his Master of Engineering degree in automatic control from Chinese Academy of Space Technology, Beijing, China, in 1989, and his Ph.D. degree in electrical and computer engineering from Washington State University, Pullman, Washington, in 1994. His current research interests include nonlinear control, robust control, time delay systems, and control applications. He was elected a member of the Board of Governors of the IEEE Control Systems Society (2008-2010, 2019-2021) and chaired the IEEE Control Systems Society Technical Committee on Nonlinear Systems and Control (2013-2015). He has served on the operating committees of several conferences and will be the General Chair of the 2028 American Control Conference. He has served on the editorial boards of several journals and is the Editor of the Birkhauser book series Control Engineering. He is a Fellow of IEEE, IFAC and AAAS.
