Abstract

The feedback control of insulin pumps for diabetic patients is discussed. Because the parameters in the mathematical model of the blood glucose dynamics present a considerable amount of uncertainty, the H-infinity framework is well suited for the design of controllers that take into account a nice compromise between robust closed-loop regulation of a constant set point and performance expressed in terms of peak values of the plasma glucose concentration.

摘要

本文讨论了糖尿病患者胰岛素泵的反馈控制。由于血糖动态数学模型中的参数存在相当大的不确定性，H∞框架非常适合设计控制器，该控制器能在恒定设定点的鲁棒闭环调节与以血浆葡萄糖浓度峰值表示的性能之间实现良好的折衷。
