流体动力学捕获允许在自由溶液中限制和操纵小物体，远离固体边界，并且不需要光场或磁场。为了在长时间尺度上实现鲁棒捕集，必须使用不同的控制方案来评估捕集器的性能，并了解系统参数对捕集器稳定性的影响。在这项工作中，我们调查的性能的水动力陷阱驱动的比例积分微分控制器的不同组合。我们进一步开发了一个基于控制的模型的陷阱，我们表征陷阱的性能范围很广的颗粒Peclet数和响应时间。总体而言，增加了解陷阱的性能将有助于改进控制器的设计，使强大的陷阱下可变的系统参数。
Hydrodynamic trapping allows for the confinement and manipulation of small objects in free solution, away from solid boundaries and without the need for optical or magnetic fields. In order to achieve robust trapping over long time scales, it is imperative to evaluate trap performance using different control schemes and to understand the effect of system parameters on trap stability. In this work, we investigate the performance of a hydrodynamic trap actuated by varying combinations of proportion-integral-derivative controllers. We further develop a control-based model of the trap, and we characterize trap performance for a wide range of particle Peclet numbers and response times. Overall, an increased understanding of trap performance will facilitate the design of improved controllers to enable robust trapping under variable system parameters.
