Modern Nonlinear control Theory As applied To Blood Glucose regulation Using High Order Sliding Mode Control

Diabetes is a serious disease during which the body s production and use of insulin is impaired, causing glucose concentration level to increase in the bloodstream. The blood glucose dynamics is described using the Bergman minimal model. In this paper, higher-order sliding mode control techniques, in specific prescribed convergence law, super-twisting control algorithm, is used to robustly stabilize the glucose concentration level of a diabetic patient in presence of the parameter variations and meal disturbance.It was shown also that the proposed schemes can perform well in simulation experiments. Finally the obtained results from these methods, are verified based on digital computer simulation by MATLAB.
