Abstract: | We propose an online method to estimate the
time-dependent time-delay of continuous glucose measurement
devices. The problem is characterized by one delayed signal
which is sampled continuously, and a reference signal which is
only available for measurement at (few) irregular time samples.
The method makes use of a forgetting function to be able
to quickly adapt to changes in the time-delay. A simulation
example and the application to blood glucose concentration data
obtained from type 1 diabetic subjects, where it is of interest to
estimate the time-delay of the continuous glucose measurement
device, show the usefulness and effectiveness of the proposed
method. |
