Modeling of Patient of Type 1 Diabetes for Blood Glucose Control

Abstract

The recent development in the insulin delivery system is the automatic one. The blood glucose levels are controlled by the feedback loop. The initial success with the simple models in normalizing blood glucose level led to the improvement of the devices including variety of control system. The insulin delivery system to diabetic is a tedious job and doesn’t ensure proper performance and leads to various complications if the delivery of insulin is not proper. The system which is a portable one used to control the blood glucose concentration. In this paper, theoretical analysis has been performed to regulate blood glucose insulin concentration on the basis of some mathematical models. The closed-loop insulin delivery system is composed of three essential components: a stable glucose sensor for measuring the glucose concentration, a control system regulating external insulin infusion based on the glucose-insulin system and a safe and stable insulin pump. The goal is to control and analyze two controllers which were designed to control the plant which is diabetic patient for this paper and the controllers analyzed are proportional integral derivative (PID), and fuzzy logic controllers (FLC). Mathematical modeling of a patient is shown in this paper. Simulation would be performed in MATLAB software.
