摘要:

通过将系统建模为混合自动机,可以分析网络物理系统。由于对混合非线性自动机进行可达性分析是一个非常具有挑战性且计算成本很高的问题,因此工程师通常尝试解决需求失效问题。一种方法是通过最小化由需求诱导的鲁棒性度量来解决失效问题。这个问题通常是非凸非光滑的问题,需要启发式和分析指导来解决。在本文中,利用混合系统的功能梯度下降法来局部降低鲁棒性度量。局部下降法与模拟退火结合作为全局优化方法,以寻找不安全行为。

英文摘要:

One way to analyze Cyber-Physical Systems is by modeling them as hybrid automata. Since reachability analysis for hybrid nonlinear automata is a very challenging and computationally expensive problem, in practice, engineers try to solve the requirements falsification problem. In one method, the falsification problem is solved by minimizing a robustness metric induced by the requirements. This optimization problem is usually a non-convex non-smooth problem that requires heuristic and analytical guidance to be solved. In this paper, functional gradient descent for hybrid systems is utilized for locally decreasing the robustness metric. The local descent method is combined with Simulated Annealing as a global optimization method to search for unsafe behaviors.
