The objective is to study and model acoustic levitation by treating it as a control system problem rather than visualizing it as a physical system problem. The specific agenda is to model the acoustic levitation system and design a controller using the obtained model; this model can be used in for "Active dust control" in a closed chamber. A test-bed needs to be developed and constructed for experimental investigation and proof of concept of particle manipulation using sonic/ultrasonic waves. Acoustic standing waves are well established physical concepts, but controlling and modeling the same is a difficult control system problem because of various non-linearity that creeps in an acoustic system at high frequency. Future work would involve in designing a robust controller using the model obtained. The same needs to be extended to the 3-d acoustic dust control system.
