Acoustic Manipulation Simulations of Single Target Particle Based on the Local Optimal Controller

摘要

Acoustic micro-nano manipulation is a kind of micro target manipulation method favored by researchers in recent years. Acoustic manipulation has the advantages of noncontact manipulation, non-singleness of manipulation objects, diversity of manipulation environment and simple and easy assembly of experimental device. Acoustic manipulation has important application prospects in biomedical engineering, precision manufacturing, robotics and acoustic metamaterials. Acoustic manipulation mainly uses the physical characteristics of sound waves to manipulate the movement of micro and nano targets, mainly including acoustic radiation force, acoustic micro eddy current, acoustic flow and Chladni effect. This paper mainly uses the experimental data based on Chladni effect to accurately simulate the linear motion of a single target, the circular trajectory of a single target and the complex trajectories of a single target by designing the local optimal selection controller. Accurate manipulation simulations provide the effective reference and verification for actual manipulation tasks, which has important engineering significance.
