摘要:

随着控制系统变得越来越复杂,迫切需要找到验证它们的系统方法。为了解决这个问题,已经有显着的工作,在开发测试生成计划的黑盒控制架构。这些计划测试一个黑盒控制架构的能力,以满足其控制目标,当这些目标表示为操作规范,通过时序逻辑公式。我们的工作扩展了这些先前的基于模型的结果,降低了黑盒系统在受到一组预先指定的环境现象时满足其操作规范的概率。我们这样做,系统地生成测试,以尽量减少Lipschitz连续稳健性措施的操作规范。我们用实验结果证明了我们的方法,其中我们表明,我们的框架可以合理地降低规范满意度的概率。

英文摘要:

As control systems become increasingly more complex, there exists a pressing need to find systematic ways of verifying them. To address this concern, there has been significant work in developing test generation schemes for black-box control architectures. These schemes test a black-box control architecture's ability to satisfy its control objectives, when these objectives are expressed as operational specifications through temporal logic formulae. Our work extends these prior, model based results by lower bounding the probability by which the black-box system will satisfy its operational specification, when subject to a pre-specified set of environmental phenomena. We do so by systematically generating tests to minimize a Lipschitz continuous robustness measure for the operational specification. We demonstrate our method with experimental results, wherein we show that our framework can reasonably lower bound the probability of specification satisfaction.
