具有切换结构的偏微分方程最优控制的凸分析方法

A convex analysis approach to optimal controls with switching structure for partial differential equations

Christian Clason, Kazufumi Ito, Karl Kunisch

摘要:

混合二进制连续控制成本的最优控制问题是具有挑战性的,因为它们缺乏凸性和弱下半连续性。用它们的凸松弛替换这些代价导致了一个原始-对偶最优性系统,该系统允许显式逐点表征,并且其Moreau-Yosida正则化服从函数空间中的半光滑牛顿方法。这种方法特别适用于计算偏微分方程的切换控制。在这种情况下,原始功能和它的松弛之间的最优性差距可以估计,并显示为零的切换结构的控制。数值例子说明了这种方法的有效性。

英文摘要:

Optimal control problems involving hybrid binary-continuous control costs are challenging due to their lack of convexity and weak lower semicontinuity. Replacing such costs with their convex relaxation leads to a primal-dual optimality system that allows an explicit pointwise characterization and whose Moreau-Yosida regularization is amenable to a semismooth Newton method in function space. This approach is especially suited for computing switching controls for partial differential equations. In this case, the optimality gap between the original functional and its relaxation can be estimated and shown to be zero for controls with switching structure. Numerical examples illustrate the effectiveness of this approach.
