In this paper, we study the identification problem of a passive system from tangential interpolation data. We present a simple construction approach based on the Mayo-Antoulas generalized realization theory that automatically yields a port-Hamiltonian realization for every strictly passive system with simple spectral zeros. Furthermore, we discuss the construction of a frequency-limited port-Hamiltonian realization. We illustrate the proposed method by means of several examples.

从频率响应数据识别哈密尔顿港系统

在本文中，我们研究了从切向插值数据中识别无源系统的问题。我们提出了一种基于 Mayo-Antoulas 广义实现理论的简单构造方法，该方法可以为每个具有简单频谱零点的严格无源系统自动生成 port-Hamiltonian 实现。此外，我们讨论了频率受限的端口汉密尔顿实现的构建。我们通过几个例子来说明所提出的方法。
