In this paper, we generalize a recently proposed
method for model reduction of linear systems to the frequencyweighted
case. The method uses convex optimization and can be
used both with sample data and exact models. We also derive
simple a priori bounds on the frequency-weighted error. We
combine the method with a rank-minimization heuristic, to
approximate multi-inputÂmulti-output systems. We also present
two applications Â environment compensation and simpli�cation
of interconnected models Â where we argue the proposed
methods are useful.
