Run the analysis for the low frequencies by running the following command:
sysfrdlow = frestimate(modellow,getlinio(modellow),inputlow);
The frequency response estimation can take several minutes. For this example, load the
estimation results.
load scdpwmharddrive_lowfreqresults.mat
To validate the low-frequency response of the identified model, compare the estimated
result with the identified model.
bode(sysid,sysfrdlow,'r*')
