RESUMO

This work presents new convex optimization procedures for full order robust H2 and H? filter design for continuous and discrete-time uncertain linear systems. The time-invariant uncertain parameters are supposed to belong to a polytope with known vertices. Thanks to the use of a larger number of slack variables and homogeneous polynomial relaxations, linear matrix inequalities for the design of robust filters can be derived from the proposed conditions, outperforming the existingmethods. The superiority and efficiency of the proposed method for robust filter design are illustrated by means of numerical comparisons in benchmark examples from the literature
