Integral-event-triggered H∞ Blood Glucose Control of Type 1 Diabetes via Artificial Pancreas

Abstract

This technical note is concerned with the event-triggered H∞ blood glucose regulation issue of type 1 diabetes by using networked artificial pancreas (AP). In order to improve the service life of AP, an integral-eventtriggered scheme (IETS) is presented to reduce the releasing rate of control signal and the updating times of insulin pump. Compared with the normal event-triggered scheme (ETS), the proposed scheme can generate a larger interevent time by utilizing the integration of the triggering condition in normal ETS. To maintain the blood glucose concentration (BGC) within standard range, the co-design conditions of triggering parameter and H∞ controller are derived by linear matrix inequalities (LMIs). Finally, the validity of the developed strategy is verified through some simulation results.

Keywords Artificial pancreas, blood glucose control, integral-event-triggered scheme.
