摘要

研究离散系统的频率加权最优模型降阶问题。给出了完全表征降阶模型的必要条件。其解由一个广义Riccati方程和两个广义Lyapunov方程组成，它们由一个投影耦合而成。在频率加权传递函数严格合适的情况下，解中出现了一个附加的投影。

Discrete-time frequency weighted model order reduction

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.<>
