论文摘要
在这项工作中，探索了海洋船的实验设计。使用了一种基于字典的方法，即从一组预定义的候选人组中选择最有用的独立实验组合的系统方法。这个想法非常笼统，但在这里量身定制为具有零均值仪器的仪器变量（IV）估计器。这种类型的估计器非常适合处理二阶模量模型的参数估计，这是一种通常用于描述海洋血管运动的模型。使用模拟和真实数据评估该方法，后者来自小型型船以及全尺寸容器。此外，修改了标准的运动规划问题，以说明信息 - 最佳子体验的先前选择，这使得以可行轨迹的形式获得完整实验的计划。
In this work, experiment design for marine vessels is explored. A dictionary-based approach is used, i.e., a systematic way of choosing the most informative combination of independent experiments out of a predefined set of candidates. This idea is quite general but is here tailored to an instrumental variable (IV) estimator with zero-mean instruments. This type of estimator is well-suited to deal with parameter estimation for second-order modulus models, which is a class of models often used to describe motion of marine vessels. The method is evaluated using both simulated and real data, the latter from a small model ship as well as from a full-scale vessel. Further, a standard motion-planning problem is modified to account for the prior-made choice of information-optimal sub-experiments, which makes it possible to obtain a plan for the complete experiment in the form of a feasible trajectory.
