RESUMO
In this work, a new method to H2robust ?ltrer design is proposed. A convex combination of Kalman ?lters, calculated in each vertex of the uncertainty polytope, is used to synthesize the robust ?lter. For this model, the best one is calculated through a convex programming problem, expressed in terms of LMIs. Inicially a sub-class of polytopic systems is considerated and later it is widened to cope with both continuous and discrete time systems subject to polytopic parameter uncertainty. Lower and upper bounds of the estimation error norm are de?ned in order to evaluate the quality of the proposed ?lter. Its order generally is greater than the order of the plant, which contributes to reduce conservatism
