Most physical processes exhibit transport delay in the measured output, and it is well known
that this can have disastrous effects on system stability and performance if it is not …

This paper deals with some issues involving a parameter estimation approach that yields
estimates consistent with the data and the given a priori information. The first part of the paper …
