Abstract

In this paper, a robust multi-objective controller is designed with \(\hbox {H}_{\infty }\) control and pole-placement constraints for the nonlinear glucose-insulin process in a type-1 diabetes patient to deliver insulin through intravenous infusion device. The concept of linear matrix inequality has been used for designing the controller. The modified Sorenson’s nonlinear model has been used and the controller is designed on \(19\mathrm{th}\) order linearized model. The resulting controller has been tested with the nonlinear patient model in presence of patient parameter variations and other uncertainty conditions. The performance of the controller was assessed in terms of its ability to track the normoglycaemic set point of 81 mg/dl with multi-meal disturbance throughout a day that yields robust performance and noise rejection.
