AI总结:

本文通过将无限时间折扣最优控制问题转化为无限维线性规划问题,证明了两者等价性,并利用矩方法近似价值函数和设计反馈控制器。

摘要:

我们重新审视确定性连续时间无限时间折扣最优控制问题的线性规划方法。第一部分中,我们将原问题松弛为一个测度空间上的无限维线性规划问题,并在较弱的假设下证明了两种形式的等价性,这比现有文献中的假设要弱得多。证明基于对偶理论和 mollification 技术,用于构造关联的 Hamilton-Jacobi-Bellman 方程的近似光滑子解。第二部分中,我们假设多项式数据,并利用 Lasserre 的 primal-dual 矩-半正定松弛层次来近似价值函数并设计近似最优反馈控制器。最后,我们给出一个示例。

英文摘要:

We revisit the linear programming approach to deterministic, continuous time, infinite horizon discounted optimal control problems. In the first part, we relax the original problem to an infinite-dimensional linear program over a measure space and prove equivalence of the two formulations under mild assumptions, significantly weaker than those found in the literature until now. The proof is based on duality theory and mollification techniques for constructing approximate smooth subsolutions to the associated Hamilton-Jacobi-Bellman equation. In the second part, we assume polynomial data and use Lasserre's hierarchy of primal-dual moment-sum-of-squares semidefinite relaxations to approximate the value function and design an approximate optimal feedback controller. We conclude with an illustrative example.
