具有可能奇异势的守恒相场系统的最优控制

Optimal control for a conserved phase field system with a possibly singular potential

P. Colli, G. Gilardi, G. Marinoschi, E. Rocca

摘要:

本文研究了具有可能奇异势的守恒型相场系统的分布控制问题。我们主要处理两种情况:在具有有界区域的粘性势的情况下,对于相变量的粘性Cahn-Hilliard型动力学的情况,以及在具有无界区域的正则势的情况下,例如经典的双阱势,标准Cahn-Hilliard方程的情况。在对数据的自然假设下,导出了最优性的一阶必要条件。

英文摘要:

In this paper we study a distributed control problem for a phase-field system of conserved type with a possibly singular potential. We mainly handle two cases: the case of a viscous Cahn-Hilliard type dynamics for the phase variable in case of a logarithmic-type potential with bounded domain and the case of a standard Cahn-Hilliard equation in case of a regular potential with unbounded domain, like the classical double-well potential, for example. Necessary first order conditions of optimality are derived under natural assumptions on the data.
