题目：Robust stabilizing controllers for systems via a time-delay approach
Abstract: This talk investigates two robust stabilizing controllers for linear uncertain systems. First, we consider a class of linear uncertain systems that is not stabilizable by output-feedback with constant gains (known as Brockett’s problem), where we suggest a new output-feedback controller that depends on a fast-varying square wave dither. Then, we study stabilization of linear uncertain systems under unknown control directions using the bounded extremum seeking controller with measurement delay. Our method is that we propose a time-delay approach to periodic averaging and to Lie-brackets-based averaging. The latter allows to present constructive quantitative results for finding the upper bound on the small parameters (and the time-delay) that ensure the stability of the original system.
