Abstract
"This thesis presents the design of a control system for a acoustophoretic filter. Acoustophoretic filtration is a process in which a pressure field is generated across a mixture of two particles, in order to separate the two without using traditional filters. Current acoustophoretic technologies are not power efficient, and cannot properly function without the use of laboratory equipment. In this work, a control system for an Acoustophoretic Filter was designed and prototyped, in order to begin removing the reliance on laboratory equipment. The control system acquired two input signals, one representing current, and the other representing voltage, and calculates the frequency and phase difference. These two parameters are then used to adjust the frequency of the signal in order to achieve maximum power transfer and trapping force. The prototype system utilized a computer, a data acquisition card installed inside of the computer, and a digital signal processor/controller. Results obtained by this prototype system indicate that the control system is feasible. Future work can derive a printed circuit board (PCB) ii version of the system, as well as increase accuracy of the algorithms and decrease execution time."
