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.
