Relaxation Methods for Hyperbolic PDE Mixed-Integer Optimal Control Problems

Falk M. Hante

摘要:

本文将基于松弛和舍入策略求解包含离散和连续控制决策的偏微分方程约束最优控制问题的收敛性分析推广到一维半线性双曲型方程组.结果得到了新的先验估计的松弛间隙的大小的基础上的特征流,不动点参数和特殊的正则性理论,这样的混合整数控制问题。作为一个应用,我们考虑一个松弛模型的最优流量切换控制的守恒律激励的交通流问题。

英文摘要:

We extend the convergence analysis for methods solving PDE-constrained optimal control problems containing both discrete and continuous control decisions based on relaxation and rounding strategies to the class of first order semilinear hyperbolic systems in one space dimension. The results are obtained by novel a-priori estimates for the size of the relaxation gap based on the characteristic flow, fixed-point arguments and particular regularity theory for such mixed-integer control problems. As an application we consider a relaxation model for optimal flux switching control in conservation laws motivated by traffic flow problems.
