Abstract:
Diabetes is a major health issue in the world. Over 8% of Americans suffer from some form of diabetes and approximately 10% of these have Type 1 diabetes. The usual treatment for these patients is to externally apply insulin so as to lower blood glucose levels. Prolonged high blood glucose levels (hyperglycaemia) can lead to long term health issues including cardiovascular disease and blindness. Extremely low blood glucose levels (hypoglycaemia) can lead to coma and even death.
 
Due to the central importance of diabetes as a public health issue, there has been substantial effort aimed at improving treatment options. In recent years, continuous blood glucose measurements (CGM) and insulin infusion pumps (IIP) have been developed. The availability of these devices has led to the possibility of autonomous closed loop control of blood glucose levels by interconnecting a CGM and an IIP via a computer based control algorithm. This is commonly termed an “Artificial Pancreas”.
The talk will emphasize control theoretic issues associated with the development of an Artificial Pancreas including;

  • Fundamental control system design limitations
  • The importance of feedforward
  • The potential advantages of preview
