摘要:

本文研究半线性抛物型偏微分方程最优控制问题的解稳定性性质。针对方程与目标泛函关于控制为仿射的问题,得到了最优解关于扰动的Hölder或Lipschitz依赖性。扰动可同时出现在方程与目标泛函中,且可关于状态变量与控制变量非线性依赖。核心结果基于对近期提出的目标泛函一阶、二阶变分联合增长性假设的拓展。本文证明了与一阶最优性必要条件组相关映射的度量次正则性这一更具普适性的结论,最优解的稳定性正是该结论的推论,该性质还可支撑近似方法的误差估计。此外,作为附带成果,本文还得到了最优控制关于Tikhonov正则化参数依赖性的Lipschitz估计。

英文摘要:

The paper investigates stability properties of solutions of optimal control problems for semilinear parabolic partial differential equations. Hölder or Lipschitz dependence of the optimal solution on perturbations are obtained for problems in which the equation and the objective functional are affine with respect to the control. The perturbations may appear in both the equation and in the objective functional and may non-linearly depend on the state and control variables. The main results are based on an extension of recently introduced assumptions on the joint growth of the first and second variation of the objective functional. The stability of the optimal solution is obtained as a consequence of a more general result obtained in the paper -- the proved metric subregularity of the mapping associated with the system of first-order necessary optimality conditions. This property also enables error estimates for approximation methods. Lipschitz estimate for the dependence of the optimal control on the Tikhonov regularization parameter is obtained as a by-product.
