It is challenging to maintain normoglycemic range of glucose concentration in type I diabetic patients. In this study H` control is applied for insulin delivery to prevent the hyperglycemic levels in a type I diabetic patient. From a -control theory point of view, the blood glucose regulation problem is reformulated as a tracking one. A glucose -tolerance curve (GTC) validated from several patients is used as reference model. Intra- and inter-patient -variability poses a -challenging task to control blood glucose concentration in diabetic patients. We develop a data based -robust -controller to control blood glucose concentration in type I diabetic (TIDM) patients in the presence of meal -disturbances under patient-model mismatch. Simulation studies are performed on the diabetic patient model under feedback control. It is seen that the proposed control strategy is able to control blood glucose concentration well within the acceptable limits and also compensate for slow parametric drifts.
