Abstract

This paper presents a dynamic model and corresponding control strategy for a micro-needle micro-pump integrated system proposed for subcutaneous insulin injection for diabetes care. The system consists of a piezoelectric micropump, multiple silicon micro-needles, insulin reservoir, wireless telemetry and remote control components. The piezoelectric micro-pump is remotely controlled through wireless telemetry. The dynamic model can be used to analyze dynamics of the integrated micro-device and develop feedback control strategy. An adaptive backstepping control with nonlinear observer is developed based on the dynamic model.
