Optimal Guaranteed Cost Control of Linear Uncertain System: an LMI Approach
摘要
Abstract
The guaranteed cost control problem for a class of linear systems with norm-bounded time-varying parameter uncertainty and a given quadratic cost function is considered. A sufficient condition for the existence of guaranteed cost state feedback controllers is presented in terms of the solvability to a certain system of linear matrix inequalities (LMIs), and the feasible solutions to the system of LMIs provide a parametrized representation of a set of guaranteed cost controllers. Furthermore, the characterization of guaranteed cost controllers is exploited to solve the optimal guaranteed cost control problem.关键词
