线性二次对偶控制

Linear Quadratic Dual Control

Anders Rantzer

AI总结:

本文基于数据驱动Riccati方程分析确定性等价自适应控制器,推导出系统稳定性和鲁棒性的充分条件,并量化激励水平与鲁棒性的相互关系。

摘要:

这是一篇最初在Arxiv上发布的草稿论文,作为CDC2023全会演讲的文档。核心材料已被L4DC 2024接收发表。本文使用“数据驱动Riccati方程”分析确定性等价自适应控制器,该方程对应于Q-learning中使用的无模型Bellman方程。该方程对数据相关矩阵呈二次依赖。这使得推导自适应系统稳定性和对未建模动态鲁棒性的简单充分条件成为可能。论文最后简短讨论了如何利用这些界限量化激励水平与鲁棒性之间的相互作用。

英文摘要:

This is a draft paper originally posted on Arxiv as a documentation of a plenary lecture at CDC2023. The core material has been accepted for publication at L4DC 2024. Certainty equivalence adaptive controllers are analysed using a ``data-driven Riccati equation'', corresponding to the model-free Bellman equation used in Q-learning. The equation depends quadratically on data correlation matrices. This makes it possible to derive simple sufficient conditions for stability and robustness to unmodeled dynamics in adaptive systems. The paper is concluded by short remarks on how the bounds can be used to quantify the interplay between excitation levels and robustness.
