网络物理系统的概率一致性

Probabilistic Conformance for Cyber-Physical Systems

Yu Wang, Mojtaba Zarei, Borzoo Bonakdarpoor, Miroslav Pajic

摘要:

在系统分析中,一致性表示两个系统同时满足相同的规范;因此,分析一个系统的结果自动转移到另一个系统,或者一个系统可以在实践中安全地取代另一个系统。在这项工作中,我们研究了信息物理系统(CPS)的概率一致性。我们提出了一个概念(近似)的概率一致性的信号时序逻辑(STL)表示的复杂规范集。基于一种新的统计测试,我们开发了第一个统计验证方法的概率一致性的广泛的一类CPS。使用该方法,我们验证了广泛使用的丰田动力系统的完整和简化模型的启动时间,基于模型预测控制和基于神经网络的汽车车道保持控制器的建立时间,以及完整和简化的电网系统的最大电压偏差的一致性。

英文摘要:

In system analysis, conformance indicates that two systems simultaneously satisfy the same set of specifications of interest; thus, the results from analyzing one system automatically transfer to the other, or one system can safely replace the other in practice. In this work, we study the probabilistic conformance of cyber-physical systems (CPS). We propose a notion of (approximate) probabilistic conformance for sets of complex specifications expressed by the Signal Temporal Logic (STL). Based on a novel statistical test, we develop the first statistical verification methods for the probabilistic conformance of a wide class of CPS. Using this method, we verify the conformance of the startup time of the widely-used full and simplified model of Toyota powertrain systems, the settling time of model-predictive-control-based and neural-network-based automotive lane-keeping controllers, as well as the maximal voltage deviation of full and simplified power grid systems.
