纳米线和纳米管的自动化、高精度操作是实现可扩展纳米制造的必要条件。然而，纳米线在其结构或组成方面表现出不受控制的变化，这可能限制其功能和特性。在本文中，我们提出了一种自适应控制器，用于利用电场同时操纵多个纳米线。然后我们证明了它在参数不确定性存在下的稳定性。无需对每根纳米线的移动特性进行复杂表征，就可以操纵纳米线达到精确控制的位置。仿真和实验结果证实了所提出的自适应控制方案能够精确地、独立地、同时地控制多根纳米线的运动。
Automated, highly precise manipulation of nanowires and nanotubes is essential to achieve scalable nanomanufacturing. However, nanowires exhibit uncontrolled variations in their structures or compositions that can limit their functions and properties. In this paper, we present an adaptive controller for the simultaneous manipulation of multiple nanowires using electric fields. We then prove its stability in the presence of parametric uncertainties. Without complex characterization of each nanowire’s mobility, the nanowires can be steered to achieve precisely controlled positions. Simulation and experimental results confirm the proposed adaptive control scheme precisely, independently, and simultaneously manipulates the motion of multiple nanowires.
