This correspondence presents a strategy for robust H2/H infin filtering design, with regional pole placement, applied to discrete- or continuous-time linear time-invariant (LTI) systems with polytope-bounded uncertainty. To overcome the conservatism of linear matrix inequality (LMI)-based formulations, the proposed design approach is based on a multiobjective optimization algorithm applied directly in the space of the filter parameters. The H2 and Hinfin norms, computed in all polytope vertices and in possible "worst case" interior points, are taken as the optimization objectives. A combination of branch-and-bound algorithm and LMI guaranteed cost formulations is applied to compute the coordinates of the worst case norms and to validate the filter design to the whole polytope. Examples are presented to illustrate the effectiveness of the proposed strategy
