AI总结:

本文提出一种数据驱动方法,通过迭代构造分段仿射Lyapunov函数并在证书违反处局部细化剖分,逐步改进未知动力系统稳定平衡点吸引域的估计。

摘要:

本文致力于动力系统的数据驱动分析,研究为未知动力系统的稳定平衡点验证其吸引域(basin of attraction)的问题。假设对于状态空间中的一组点,可以获得控制系统常微分方程右端项的逐点求值。在技术层面,将利用基于优化的技术迭代构造分段仿射Lyapunov函数,以有效验证相关证书。作为主要贡献,当这些证书在局部被违反时,将对定义域及其相关的剖分进行细化,从而改进对吸引域的描述。

英文摘要:

The paper is dedicated to data-driven analysis of dynamical systems. It deals with certifying the basin of attraction of a stable equilibrium for an unknown dynamical system. It is supposed that point-wise evaluation of the right-hand side of the ordinary differential equation governing the system is available for a set of points in the state space. Technically, a Piecewise Affine Lyapunov function will be constructed iteratively using an optimisation-based technique for the effective validation of the certificates. As a main contribution, whenever those certificates are violated locally, a refinement of the domain and the associated tessellation is produced, thus leading to an improvement in the description of the domain of attraction.
