我们正在开发一种随机的方法来测试生成的混合动力系统,控制系统一般,使用机器人路径规划已被证明是成功的解决高维非线性问题的技术。所提出的算法的一个关键组成部分是“度量”的选择-如何决定两个状态的接近度-这是非平凡的混合状态空间。在本文中,我们介绍了四个指标的混合动力系统和基准的算法,使用这些指标的一个流行的例子从文献中的问题,并比较度量的选择对计算效率的影响。
We are developing a randomized approach to test generation for hybrid systems, and control systems in general, using techniques from robotic path planning which have proved successful in solving high dimensional nonlinear problems. A critical component of the proposed algorithm is the choice of "metric" - how one decides the closeness of two states - which is nontrivial in the hybrid state space. In this paper we introduce four metrics for hybrid systems; and benchmark the algorithm using each of these metrics on a popular example problem from the literature and compare the impact of metric choice on computational efficiency.
