  In this paper, we analyse the consistency of the Simplified Refined
Instrumental Variable method for Continuous-time systems (SRIVC). It is well
known that the intersample behaviour of the input signal influences the quality
and accuracy of the results when estimating and simulating continuous-time
models. Here, we present a comprehensive analysis on the consistency of the
SRIVC estimator while taking into account the intersample behaviour of the
input signal. The main result of the paper shows that, under some mild
conditions, the SRIVC estimator is generically consistent. We also describe
some conditions when consistency is not achieved, which is important from a
practical standpoint. The theoretical results are supported by simulation
examples.
