Abstract: This research aims to enhance the efficiency of a valveless piezoelectric miniature pump through the implementation of feedback control. Finite element analysis reveals that the motion of the structure impacts pumping efficiency. Using plant identification, a linear finite-element model of the miniature pump is reduced to a single-mode model with a single input. To increase the pumping efficiency, a closed-loop tracking control based on a nonlinear control technique, i.e. exact feedback linearization, is employed. The closed-loop miniature pump outperforms the open-loop miniature pump in terms of settling time and the pressure load existence at an outlet of the miniature pump, also improving efficiency by tracking a reference signal with two frequencies.
