摘要

与其他悬浮技术相比，声学悬浮是一种极具吸引力的多功能技术，在粒度、范围、可重构性和易用性方面具有多项优势。在本文中，我们研究了如何利用主动阻尼来改善空气中声学悬浮器的响应时间和定位精度。我们使用激光多普勒测振仪测量悬浮粒子的速度。利用这一信息，我们设计并实施了一种控制算法，以提供主动阻尼。通过系统识别和建模，我们证明主动阻尼器机制可以通过模型很好地预测，并且可以通过电子方式重新配置和控制。

Active damping for acoustic levitation in air

Acoustic levitation is an attractive and versatile technique that offers several advantages in terms of particle size, range, reconfigurability, and ease of use with respect to alternative levitating techniques. In this paper, we study the use of active damping to improve the response time and positioning precision of an acoustic levitator operating in air. We use a laser Doppler vibrometer to measure the velocity of a levitated particle. Using this information, a control algorithm is designed and implemented to provide active damping. By system identification and modeling, we demonstrate that the active damper mechanism is well-predictable by models and can be electronically reconfigured and controlled.

期刊介绍： AIP Advances is an open access journal publishing in all areas of physical sciences—applied, theoretical, and experimental. All published articles are freely available to read, download, and share. The journal prides itself on the belief that all good science is important and relevant. Our inclusive scope and publication standards make it an essential outlet for scientists in the physical sciences. AIP Advances is a community-based journal, with a fast production cycle. The quick publication process and open-access model allows us to quickly distribute new scientific concepts. Our Editors, assisted by peer review, determine whether a manuscript is technically correct and original. After publication, the readership evaluates whether a manuscript is timely, relevant, or significant.
