A Priori Error Analysis for an Optimal Control Problem Governed by a Variational Inequality of the Second Kind

Christian Meyer, Monika Weymuth

We consider an optimal control problem governed by an elliptic variational inequality of the second kind. The problem is discretized by linear finite elements for the state and a variational discrete approach for the control. Based on a quadratic growth condition we derive nearly optimal a priori error estimates. Moreover, we establish second order sufficient optimality conditions that ensure a quadratic growth condition. These conditions are rather restrictive, but allow us to construct a one-dimensional locally optimal solution with reduced regularity, which serves as an exact solution for numerical experiments.

第二类变分不等式最优控制问题的先验误差分析

我们考虑由第二种椭圆变分不等式控制的最优控制问题。通过状态的线性有限元和控制的变分离散方法将问题离散化。基于二次增长条件,我们得出了几乎最佳的先验误差估计。此外,我们建立了确保二次增长条件的二阶充分最优条件。这些条件是限制性的,但是允许我们构造具有减小的规则性的一维局部最优解,这可以作为数值实验的精确解。
