Hey everyone, just want to make sure I am thinking of modulation frequency, fmod, correctly. fs is the switching frequency and basically fmod is how often I am adjusting the switching frequency, is that correct? So in a real system, fmod would be fixed value, a lower value for slower output regulation, and a higher value for faster output regulation, correct?
Also, the 's' in Genv(s) is the modulation freq (s = j*2*pi*fmod), correct?
Thanks for the clarification.

As I understand it, Charlie, you have it essentially correct. fmod is the frequency at which you vary the frequency (FM) or the amplitude (AM) of the sinusoid. It will be a "low" frequency sinusoid, but does not always have to be a fixed value (in communications the modulation frequency can vary somewhat).
For Genv(s), you are looking for s = wmod*j
