摘要

我们结合能量稳定和端口-哈密顿（pH）系统得到能量稳定的端口-哈密顿（es-pH）系统。这个想法是用一个输入输出端口扩展已知的能量稳定系统，从而得到一个pH公式。新的es-pH公式的一个优点是它在整个离散化（在空间和时间上）和模型简化过程中自然地保留了es-pH结构。

Energy-stable port-Hamiltonian systems

We combine energy-stable and port-Hamiltonian (pH) systems to obtain energy-stable port-Hamiltonian (es-pH) systems. The idea is to extend the known energy-stable systems with an input–output port, which results in a pH formulation. One advantage of the new es-pH formulation is that it naturally preserves its es-pH structure throughout discretization (in space and time) and model reduction.

期刊介绍： The purpose of Applied Mathematics Letters is to provide a means of rapid publication for important but brief applied mathematical papers. The brief descriptions of any work involving a novel application or utilization of mathematics, or a development in the methodology of applied mathematics is a potential contribution for this journal. This journal''s focus is on applied mathematics topics based on differential equations and linear algebra. Priority will be given to submissions that are likely to appeal to a wide audience.
