Analysis and Comparison of Port-Hamiltonian Formulations for Field Theories - demonstrated by means of the Mindlin plate
摘要：
本文主要研究由偏微分方程描述的系统的端口哈密顿形式。基于变分原理，我们推导出的运动方程，以及在著名的拉格朗日框架的边界条件。然后，它是感兴趣的重新制定的运动方程在端口的哈密顿设置，在那里我们比较的方法的基础上斯托克斯-狄拉克结构的哈密顿设置，使使用所涉及的束结构类似的变分方法的基础上。我们将使用Mindlin板，一个具有二维空间域的分布参数系统，作为运行示例。
英文摘要：
This paper focuses on the port-Hamiltonian formulation of systems described by partial differential equations. Based on a variational principle we derive the equations of motion as well as the boundary conditions in the well-known Lagrangian framework. Then it is of interest to reformulate the equations of motion in a port-Hamiltonian setting, where we compare the approach based on Stokes-Dirac structures to a Hamiltonian setting that makes use of the involved bundle structure similar to the one on which the variational approach is based. We will use the Mindlin plate, a distributed parameter system with spatial domain of dimension two, as a running example.
