In this paper, we consider an H∞ problem using unstable weighting functions. Such weights are used to achieve asymptotic disturbance attenuation and/or asymptotic reference tracking, and they cannot be handled by the standard H∞ control theory. For this problem, we present necessary and sufficient conditions to exist a solution using Riccati inequalities. This conditions need no assumptions on the jω invariant zeros of G12 and G21
