摘要

本文提出了一种针对时变延迟输入的血糖调节控制策略,其中延迟未知。该控制方案基于基于观测器的线性状态相关(LSD)控制(一般线性参数变化(LPV)框架的一个子类),具有H∞准则。这种建议的控制调节葡萄糖水平,以响应膳食摄入量。采用一种新颖的LSD系统表示来放松非线性系统固有的保守性。首先,观测器在输入延迟的情况下获得当前状态向量的估计,其中时变未知延迟可能相对较长。因此,控制律在存在较长的未知延迟时仍能很好地工作。通过考虑不同膳食干扰和未知延迟情况,验证了基于观测器的控制方案。

Observer-based linear state-dependent control for blood glucose regulation in type 1 diabetic patients with unknown delays
This paper presents a control strategy for blood glucose regulation in the presence of a time-varying delayed input, where the delay is unknown. The proposed control scheme is based on an observer-based linear state-dependent (LSD) (a subclass of the general linear parameter varying (LPV) framework) control with H criterion. This proposed control regulates glucose levels in response to meal intake. A novel LSD system representation is used to relax the inherent conservativeness of the nonlinear system. First, the observer achieves an estimate of the current state vector despite the delayed input, where the time-varying unknown delay can be relatively long. Thus, the control law will perform well in the presence of a long unknown delay. The observer-based control scheme is validated by considering different meal disturbances and unknown delay scenarios.
