摘要:

哈密顿-雅可比(HJ)可达性分析是保证动力系统性能和安全性的关键形式验证方法;过去十年中已应用于许多小规模系统。其优势包括兼容一般非线性系统动力学、对有界扰动的正式处理以及有完善的数值工具。主要挑战是解决其对状态变量数量的指数计算复杂性。在本教程中,我们概述了基本的HJ可达性理论,并提供使用最新数值工具的指导,包括高效GPU并行实现的水平集工具箱用于计算可达集。此外,我们回顾了当前在高维HJ可达性中的工作,展示如何通过各种通用理论和应用特定见解缓解维度挑战。

英文摘要:

Hamilton-Jacobi (HJ) reachability analysis is an important formal verification method for guaranteeing performance and safety properties of dynamical systems; it has been applied to many small-scale systems in the past decade. Its advantages include compatibility with general nonlinear system dynamics, formal treatment of bounded disturbances, and the availability of well-developed numerical tools. The main challenge is addressing its exponential computational complexity with respect to the number of state variables. In this tutorial, we present an overview of basic HJ reachability theory and provide instructions for using the most recent numerical tools, including an efficient GPU-parallelized implementation of a Level Set Toolbox for computing reachable sets. In addition, we review some of the current work in high-dimensional HJ reachability to show how the dimensionality challenge can be alleviated via various general theoretical and application-specific insights.
