【Abstract】 The problem of robust stability for LQ guaranteed cost control of structured and unstructured uncertain linear systems is considered. First of all, some definitions about the problem are proposed. Then, robustness bounds for LQ guaranteed cost control systems with unstructured and a kind of structured uncertainties are derived. Furthermore, for structured uncertain systems, an algorithm to optimize the robustness bounds by choosing appropriate parameters as well as the relevant design technique are presented in the paper. Additional, a robustness analysis procedure of LQ guaranteed cost control systems for structured uncertainties is established. An example is given to illustrate the proposed methods.更多还原
