摘要
This paper deals with guaranteed H-2 norm computation for continuous-time uncertain linear systems in convex bounded domains. As main result, we show that a special choice for the parameter-dependent Gramian solution allows us to establish a convergent sequence of polynomially parameter-dependent linear matrix inequalities whose solutions are constant symmetric matrices parametrized in terms of an integer K. Then, we propose some linear matrix inequality relaxations to numerically compute the H-2 guaranteed cost and we investigate the trade off between accuracy of the results and computational effort.
