Pierluigi Colli, Gianni Gilardi, Gabriela Marinoschi

摘要:

本文讨论了具有温度动态边界条件的Caginalp型相场系统的最优控制问题。置于动态边界条件中的控制作用于边界的一部分。本文的分析证明了一般的一类可能是奇异的势的最优控制的存在性。这项研究包括潜在的衍生物可能不存在,这些被取代的定义明确的次微分。在对结构参数和势函数的较强假设下(即正则和对数情形下具有单值导数),导出了一阶最优性必要条件最优性条件,并用第一伴随变量的边界迹表示.

英文摘要:

This paper deals with an optimal control problem related to a phase field system of Caginalp type with a dynamic boundary condition for the temperature. The control placed in the dynamic boundary condition acts on a part of the boundary. The analysis carried out in this paper proves the existence of an optimal control for a general class of potentials, possibly singular. The study includes potentials for which the derivatives may not exist, these being replaced by well-defined subdifferentials. Under some stronger assumptions on the structure parameters and on the potentials (namely for the regular and the logarithmic case having single-valued derivatives), the first order necessary optimality conditions are derived and expressed in terms of the boundary trace of the first adjoint variable.
