Chaotic dynamic analysis and nonlinear control of blood glucose regulation system in type 1 diabetic patients
In this paper, chaotic dynamic and nonlinear control in a glucose-insulin system in types I diabetic patients and a healthy person have been investigated. Chaotic analysis methods of the blood glucose system include Lyapunov exponent and power spectral density based on the time series derived from the clinical data. Wolf's algorithm is used to calculate the Lyapunov exponent, which positive val...
متن کاملIntelligent blood glucose control in diabetic patients: design and simulation of an artificial pancreas
Background: Diabetes mellitus (DM) is a common chronic disease with diverse complications. About 10% of the earth's population suffer from this disease. For smart control of the blood glucose in DM patients, an artificial pancreas was designed and simulated by a predictive sliding mode controller considering the time delay of insulin effect. Method: In this method, one of the time-delay glucos...
متن کاملPerioperative control of blood glucose
This review mainly focuses on the management of type 2 diabetes in the preoperative setting with a special emphasis on intraoperative glycemic control. Some patients learn their diagnosis of diabetes just prior to the surgery. The prevalence of previously undiagnosed diabetes is reported to be 5.2-10% in literature. Treatment protocols must be tailored individually but evidence based approach i...
متن کاملRobust Adaptive Neural Control of the Blood Glucose for Type 1 Diabetic Patients in Presence of Meals
In this paper, the blood glucose control for type 1 diabetic patients in the presence of model uncertainties and uncertain meals is considered. In order to present an efficient control approach, it is assumed that the dynamics describe the mechanism of the blood glucose regulation in type 1 diabetic patients are completely unknown. Hence, based on the universal approximation property of the rad...
متن کاملBlood glucose control in the trauma patient.
Hyperglycemia can be a significant problem in the trauma population and has been shown to be associated with increased morbidity and mortality. Hyperglycemia in the trauma patient, as in other critically ill patients, is caused by a hypermetabolic response to stress and seems to be an entity of its own rather than simply a marker. Although several early studies in a mixed intensive care unit po...
