摘要

我们考虑二维粘性Cahn—Hilliard—Oberbeck—Boussinesq系统的最优控制问题，该系统的控制在正则Borel测度空间中取值。状态方程模拟了两种不可压缩非等温粘性流体之间的相互作用。在控制浓度、平均速度和温度的动力学方程中，应用带有约束的局部分布控制。用拉格朗日定理证明了局部最优性的充分必要条件。这些条件将通过相关伴随系统的正则性结果、相对于状态空间的弱范数的线性化系统解的先验估计以及Borel测度的Lebesgue分解得到。

Optimal Borel measure-valued controls to the viscous Cahn--Hilliard--Oberbeck--Boussinesq phase-field system on two-dimensional bounded domains

We consider an optimal control problem for the two-dimensional viscous Cahn--Hilliard--Oberbeck--Boussinesq system with controls that take values in the space of regular Borel measures. The state equation models the interaction between two incompressible non-isothermal viscous fluids. Local distributed controls with constraints are applied in either of the equation governing the dynamics for the concentration, mean velocity, and temperature. Necessary and sufficient conditions characterizing local optimality in terms of the Lagrangian will be demonstrated. These conditions will be obtained through regularity results for the associated adjoint system, a priori estimates for the solutions of the linearized system in a weaker norm compared to that of the state space, and the Lebesgue decomposition of Borel measures.
