Yiming Meng, Taha Shafa, Jesse Wei, Melkior Ornik

AI总结:

本文提出一种仅需局部动态和变化率界等有限先验知识,通过在线学习轨迹动态与代理动态综合控制,将未知非线性系统驱动至可达状态邻域的新方法。

摘要:

本文提出了一种新颖的方法,用于在系统动态模型先验知识有限的情况下,将非线性系统驱动至期望状态:仅需单点的局部动态以及这些动态变化率的界。该方法利用沿轨迹的局部学习动态(基于截至当前时刻可用的数据)以及已知的代理动态来综合控制动作,其中代理动态能够生成未知系统真实可达集的下近似。本文贡献的一个重要优势在于,执行所提出的控制方法所需的知识极少。我们建立了充分条件,以确保受控轨迹在短时间内到达任何可证明可达状态的邻域,其精度取决于这些条件的可调参数。

英文摘要:

In this paper, we present a novel method to drive a nonlinear system to a desired state, with limited a priori knowledge of its dynamic model: local dynamics at a single point and the bounds on the rate of change of these dynamics. This method synthesizes control actions by utilizing locally learned dynamics along a trajectory, based on data available up to that moment, and known proxy dynamics, which can generate an underapproximation of the unknown system's true reachable set. An important benefit to the contributions of this paper is the lack of knowledge needed to execute the presented control method. We establish sufficient conditions to ensure that a controlled trajectory reaches a small neighborhood of any provably reachable state within a short time horizon, with precision dependent on the tunable parameters of these conditions.
