Robust Blood Sugar Monitoring in Diabetic Patients
with Timing Jitter due to Human Factors
Authors: , , ,
Abstract: Blood sugar monitoring in diabetic patients is commonly provided with timing jitter caused by human factors. In this paper we address the problem by developing the robust $$H_{2}$$ optimal finite impulse response (OFIR) filter under under possible disturbances, initial errors, and measurement errors. The filter is applied to data collected daily before breakfast from diabetic patients. It is shown that the robust $$H_{2}$$-OFIR filter improves the accuracy of the OFIR filter by the factor of less than the fractional time jitter. That is, for large fractional timing jitter of 10% the improvement would be less than 10% that is small. Otherwise, it is worth using robust estimators.
