I'm trying to use this for my thesis, but the MOESP and N4SID algorithms seem not to give the right values. I'm using an input u in the form u = 5 * sin(0.3t) computing the output through scipy.signa…

This is an issue carried forward from when this was hosted on the github.gatech.edu domain. In the interest of resolving it, I will past my comments below.
