Frequency-Limited H-infinity Model Reduction for Positive Systems

Li, Xianwei; Yu, Changbin (Brad); Gao, Huijun


In this paper, the problem of frequency-limited H∞ model reduction for positive linear time-invariant systems is investigated. Specifically, our goal is to find a stable positive reducedorder model for a given positive system such that theH∞ norm of the error system is bounded over a frequency interval of interest. A new condition in terms of matrix inequality is developed for characterizing the frequency-limited H∞ performance. Then an equivalent parametrization of a positive...[Show more]
