Robust and fault-tolerant strategies for controlling blood glucose in patients with type 1 diabetes

Type 1 diabetes is a serious disease that must be monitored and controlled artificially by supplying exogenous insulin to the body. The artificial pancreas (AP) is a closed-loop system that resulted from integrating an insulin pump with a CGM and uses a control algorithm to automate insulin infusion...

Descrição
Resumo:Type 1 diabetes is a serious disease that must be monitored and controlled artificially by supplying exogenous insulin to the body. The artificial pancreas (AP) is a closed-loop system that resulted from integrating an insulin pump with a CGM and uses a control algorithm to automate insulin infusion. In this work, a novel tuning system and a multivariable control approach are presented for an AP system aimed to be robust against patient variability, meals and exercise. To enhance safety, fault detection 2/2 strategies are also developed as an integral part of the system. The approaches have been extensively validated in simulation and in an inpatient clinical trial
