Today we got a handle on the sysidexample.m matlab file, and the tfestimate function. Below is a plot of a second-order system simulated and run through TFestimate, green circles are analytical results, blue line is from TFestimate in all plots:
We explored changing sample frequency and period. As expected, reduced sample frequency led to undefined high frequency behavior prediction, and reduced sample period limits low frequency behavior. See plots below:
Low (100Hz) Frequency
