Abstract
Diabetes has been introduced as the sixth leading cause of death in the world. Type 1 diabetic patients should be injected insulin to keep their blood glucose at a safe level range. Due to an excessive increase in insulin injection can cause human death, it should be completely closed-looped controlled. On the other hand, the delayed nonlinear model of the glucose-insulin system makes some challenges in its control. In this paper, an improved sliding mode control (SMC) technique is proposed to regulate patients’ blood glucose levels and suffer type 1 diabetes. The proposed improved SMC (ISMC) determines the pumping rate of insulin as a control signal in the closed-loop control. Simulation results demonstrate that the patient’s blood glucose is regulated by optimal insulin injection rate. Compared to classical SMC, the proposed ISMC has higher accuracy and a more efficient control signal.
