论文摘要
近年来，由于哈米尔顿港系统在建模和控制中的固有宝贵特性，近年来引起了很多关注。在本文中，我们有兴趣从时间域输入输出数据构建线性端口 - 哈米尔顿系统。我们讨论了一种非侵入性方法，该方法由两种主要成分组成 - （a）从时间域数据推断频率响应数据，以及（b）使用推断的频率响应数据来构建基础港口 - 哈米尔顿港的实现。我们通过两个数值示例说明了提出的方法，并将其与其他两种系统识别方法进行比较，以从输入输出数据中推断频率响应。
Port-Hamiltonian systems have gained a lot of attention in recent years due to their inherent valuable properties in modeling and control. In this paper, we are interested in constructing linear port-Hamiltonian systems from time-domain input-output data. We discuss a non-intrusive methodology that is comprised of two main ingredients -- (a) inferring frequency response data from time-domain data and (b) constructing an underlying port-Hamiltonian realization using the inferred frequency response data. We illustrate the proposed methodology by means of two numerical examples and also compare it with two other system identification methods to infer the frequency response from the input-output data.
