Abstract
The problem of frequency-weighted optimal model order reduction for discrete-time systems is considered. Necessary conditions completely characterizing the reduced-order model are given. The solution consists of a set of one generalized Riccati equation and two generalized Lyapunov equations all coupled by a projection. In the case when the frequency-weighting transfer function is strictly proper an additional projection appears in the solution
