Jan 13, 2020 · First gut feeling: I would expect no blow-up as the cosine oscillates and hence the integrator should give us again a harmonic of the same frequency. The system is linear after all. Also, its transfer function does not have a singularity for any nonzero frequency, so again, no blow-up expected, things should work nicely.

It looks like it's just a couple of low pass filters followed by an integrator. Its response to a step function should be to integrate to ...If the delay is not a whole multiple of the sample time then when substituting $(2)$ in $(5)$ allows one to split the integral into two parts, such that each partial integral is only a function of one of the discrete sampled inputs and thus can be factored out of the integral. If the delay is a whole multiple of the sample time then the ...

In addition, the offsets in the 2nd and the 3rd integrator can be equivalent to the offset of 1st integrator.
