Diseño de controladores robustos aplicados a un modelo de páncreas artificial de un paciente virtual con diabetes tipo 1.: diseño y simulación de un controlador PID Robusto basado en conceptos de control por modos deslizantes aplicado al modelo de glucosa - insulina de Hovorka para pacientes con diabetes tipo 1.

Abstract

Diabetes is a chronic disease and is currently considered one of the main causes of death in people around the world, its treatment is complex, and it is very difficult to control glucose levels, especially when the patient eats food and even more when this therapy depends clearly on the person who suffers from this disease. In recent years, advanced technologies have been proposed for the development of infusion equipment that allows optimal and adequate control of blood glucose, these necessarily use controllers that can keep the patient within normal limits. The present work proposes the implementation of a robust PID controller based on concepts of control by sliding modes in the Hovorka glucose-insulin model, for three different patients in three different food intake scenarios, the results obtained are validated by comparing of the ISE and ISCO performance indices between the proposed controller and a traditional PID controller, in addition these control laws are implemented in the UVa/Padova simulator to verify their performance.
