AI总结:

本文通过定义在单纯流形上的单纯Dirac结构,将分布式参数端口-哈密顿系统离散化为有限维端口-哈密顿系统,并探讨了结构不变量的存在性及其在能量成形中的应用。

摘要:

单纯Dirac结构作为经典Stokes-Dirac结构的有限类比,捕捉系统的拓扑规律,在单纯流形上通过由余边界算子关联的原始和对偶上链定义。这些有限维Dirac结构为制定标准输入-输出有限维端口-哈密顿系统提供了框架,这些系统模拟了分布式参数端口-哈密顿系统的行为。本文详细阐述了单纯Dirac结构的矩阵表示以及在单纯流形上由此产生的端口-哈密顿系统。利用这些表示,我们考虑了结构不变量的存在性,并展示了它们如何与单纯流形上端口-哈密顿系统的能量成形相关。

英文摘要:

Simplicial Dirac structures as finite analogues of the canonical Stokes-Dirac structure, capturing the topological laws of the system, are defined on simplicial manifolds in terms of primal and dual cochains related by the coboundary operators. These finite-dimensional Dirac structures offer a framework for the formulation of standard input-output finite-dimensional port-Hamiltonian systems that emulate the behavior of distributed-parameter port-Hamiltonian systems. This paper elaborates on the matrix representations of simplicial Dirac structures and the resulting port-Hamiltonian systems on simplicial manifolds. Employing these representations, we consider the existence of structural invariants and demonstrate how they pertain to the energy shaping of port-Hamiltonian systems on simplicial manifolds.
