This paper presents a mixed H2 / H∞ balanced realization and applies this to model reduction. Mixed H2 / H∞ balanced realization is a state space description such that solutions of H2 Lyapunov equation and H∞ Riccati equation become diagonal matrices simultaneously. It is shown that H∞ and H2 norms of any reduced model based on this realization are not greater than those of the original system respectively. Upper bounds of H∞ norm and H2 norm of the error system between the original model and the reduced model are also established.
