Abstract

Low gain feedback refers to certain families of stabilizing state feedback gains that are parameterized in a scalar and go to zero as the scalar decreases to zero. Low gain feedback was initially proposed to achieve semi-global stabilization of linear systems subject to input saturation, and was later found to be effective in dealing with control systems with time delays. It can also be combined with high gain feedback in different ways for solving various control problems. In this talk, we discuss the concept of low gain feedback, its properties, its design methods and its applications.
