基于密度函数的鲁棒数据驱动安全控制

Robust Data-Driven Safe Control using Density Functions

Jian Zheng, Tianyu Dai, Jared Miller, Mario Sznaier

摘要:

本文提出了一个数据驱动的鲁棒安全控制律综合框架。给定噪声的实验数据和一些关于系统结构的先验知识,目标是合成一个状态反馈律,使得即使在存在未知但有界干扰(过程噪声)的情况下,闭环系统的轨迹也能保证避免不安全集。本文的主要结果表明,对于多项式动力学,通过将多项式优化中的元素与择一定理相结合,可以将该问题归结为一个易于处理的凸优化问题。这种优化提供了合理的控制律和密度函数安全证书。数值例子说明了这些结果。

英文摘要:

This paper presents a tractable framework for data-driven synthesis of robustly safe control laws. Given noisy experimental data and some priors about the structure of the system, the goal is to synthesize a state feedback law such that the trajectories of the closed loop system are guaranteed to avoid an unsafe set even in the presence of unknown but bounded disturbances (process noise). The main result of the paper shows that for polynomial dynamics, this problem can be reduced to a tractable convex optimization by combining elements from polynomial optimization and the theorem of alternatives. This optimization provides both a rational control law and a density function safety certificate. These results are illustrated with numerical examples.
