Add to ORKGInternational audienceModel approximation of multiple-inputs/multiple-outputs (MIMO) linear dynamical systems over a bounded frequency range can be expressed as an optimization problem in terms of the frequency-limited H2-norm. In this paper, a new formulation of the frequency-limited H2 model approximation error is presented and its gradient derived. It is then used in a descent algorithm which does not require to solve any Lyapunov equation but one initial eigenvalue problem. The efficiency of the method is illustrated through numerical benchmarks
